How Far From Airport Should You Live if You Fly for Work

A 6:40 a.m. departure out of Nashville means leaving Chattanooga at three in the morning. That is not really a departure time. It is a decision to give up a night's sleep, made months earlier, by whoever picked which town to live in.

Most relocation sheets handle air travel with a single question: how far is the airport. It is the wrong measurement, and it is wrong in a way that can be proved from published data. In the first quarter of 2026 the Department of Transportation recorded a fare premium of 21.4% at Chattanooga and a fare discount of 20.9% at Asheville. The two airports appear in almost exactly the same number of markets. Neither number has anything to do with how long it takes to get to the curb.

What follows is the lookup path for four free federal datasets that between them price the travel line of a relocation: the airfare your future neighbors actually paid, the premium your candidate airport charges, the class and trajectory of that airport, and the federal reimbursement caps that give you a defensible figure for the hotel you will end up booking the night before. Everything below was read on 9 September 2026. All of it is quarterly or annual, so it will have moved by the time you use it, and every screen is one you can open yourself.

The fare your future neighbors paid is published four times a year

The Department of Transportation runs a survey called the Airline Origin and Destination Survey, known everywhere by its form number, DB1B. The TranStats data directory describes it in one line: "Origin and Destination Survey (DB1B) is a 10% sample of airline tickets from reporting carriers. Data includes origin, destination and other itinerary details of passengers transported."

Out of that sample the department builds the Consumer Airfare Report, and the useful part of it for anyone comparing towns is Table 6. Its own description says it "lists all city-pair markets in the contiguous United States that average at least 10 passengers each day," and that "all records are aggregated as directionless city pair markets," meaning traffic in both directions is added together.

Open Table 6 on the department's open data portal. The most recent release when I read it was the first quarter of 2026, posted 3 September 2026, covering 6,313 markets. Filter on year and quarter first, then on city1 or city2. The columns worth reading:

Three things about this table trip people up.

The first is that a missing market is information. If your candidate town and your destination do not appear together, the market carries fewer than 10 passengers a day and there is no fare series for it at all. That is worth knowing before you promise your employer you can be in the office on Tuesday mornings.

The second is that fare_low misleads if you read it as "the price I can get." Asheville to New York City shows an average fare of $200.74 for the quarter and a low-fare-carrier figure of $83 from Allegiant. Allegiant carried 16% of that market. A carrier with a sixth of the passengers is not flying every day, and a fare you can only buy on two days of the week is not a business travel fare. Read fare_low as evidence that a discount carrier is present, which matters enormously, and read fare as the number for your sheet.

The third is that these are averages of tickets already sold across a whole quarter, including the ones bought four months out by people with flexible dates. They are a fair basis for comparing two towns against each other. They are not a quote.

Twenty-one percent, and it has nothing to do with the runway

The same report has a table almost nobody uses, and it is the one that answers the question in the title. Table 7 publishes, per airport, "fare premiums for airports in the top 1,000 city pairs," and says outright what it is for: it "demonstrates the impact of low-fare service and hub domination on fare levels."

One warning before you read it. The percentage columns are stored as decimal fractions. A totalperprem of 0.21405 is a premium of 21.4%, not 0.2%. Read them as percentages and every airport in the country appears to sit within half a percent of the national benchmark, which is the tell that you are off by two decimal places.

Here is the first quarter of 2026 for a set of southeastern airports, with the two Tennessee ones at the top.

Read down the premium column and the size story falls apart immediately. Atlanta is the busiest passenger airport in the country and it carries a premium of nearly 17%. Charlotte carries almost 19%. Asheville, which appears in barely a third as many markets as Atlanta, sits more than 20% below the benchmark.

Now read the low-cost-service column alongside it and a pattern appears, with one exception that is itself the point. Chattanooga and Huntsville, the two airports where fewer than a fifth of passengers are in markets a discount carrier serves, are the two carrying premiums above 21%. Asheville and Knoxville, where half to two-thirds of passengers have that option, are the two below the line. Nashville, at 93.6%, sits essentially at the benchmark.

The exception is Atlanta and Charlotte, where discount carriers are present in the great majority of markets and the premium is high anyway. That is the second effect the table's own description names: hub domination. When one airline controls the connecting bank, its ability to price the local passenger does not disappear because a competitor flies to Orlando.

So the operating question for a shortlist is not how big the airport is. It is this: in the markets I actually fly, does a low-cost carrier operate, and does one airline own this airport? Table 7 answers both in a single row.

Table 7 covers only airports appearing in the top 1,000 city pairs with more than 20 passengers a day, so smaller fields are not listed. If your candidate airport is missing, that absence is itself a finding, and you fall back to Table 6 for the individual markets you care about.

Six destinations, two Tennessee airports, one column of differences

The premium is a summary across every market at an airport. Your sheet needs the markets you personally fly, which is a different and usually larger number.

Say the job requires the head office in Dallas, a client in New York, quarterly reviews in Washington, an engineering site in Chicago, an annual conference in Denver, and one trip a year to the coast. Six destinations. Here is the first quarter of 2026 for both Tennessee airports.

Two details in that table earn their place. Chicago is nearly a wash, at eleven dollars. San Francisco is a hundred and twenty-seven. If the job sends you to Chicago and nowhere else, this entire subject is worth about a hundred and thirty dollars a year and you can stop reading. If it sends you west, the same pair of towns is a different decision.

The other detail is a cross-check worth doing every time. Across all of its markets, Chattanooga's average fare in Table 7 was $62.53 above Nashville's. Across the six destinations above, the gap is $83.05. The all-markets figure is diluted by leisure routes to Florida that this particular traveller never flies. That difference, twenty dollars a trip, is the whole argument for pulling your own destinations instead of accepting an airport-level average.

The passenger counts say something the fares do not. Chattanooga appears in 50 markets in Table 6, carrying 1,878 passengers a day in total. Nashville appears in 147, carrying 32,764. Chattanooga to San Francisco moves 35 passengers a day across the entire market. A market that thin is one schedule change away from becoming a market that requires two connections.

The drive is priced twice, and the two prices disagree

Now the other side of the ledger, and this is where most people's arithmetic quietly collapses.

Call the drive 135 road miles each way. Measure your own rather than trusting that figure, and measure it at the hour you would actually leave, using the departure-time method in the piece on measuring the drive time you will really have. A 4 a.m. run up the interstate and a 5 p.m. run back are not the same road.

That is 270 miles round trip, and there are two defensible ways to price it.

The full-cost basis is the IRS standard mileage rate, which the agency sets at 76 cents a mile for business use from 1 July through 31 December 2026, raised from 72.5 cents in the first half of the year. That rate is meant to cover fuel, maintenance, tyres, insurance and depreciation. It gives $205.20 for the round trip.

The marginal basis is fuel only, on the argument that the car exists regardless. The Energy Information Administration's weekly retail gasoline and diesel prices put the U.S. average for regular at $4.071 a gallon, including taxes, for the week of 31 August 2026. At 30 miles to the gallon, 270 miles burns 9 gallons, which is $36.64.

Twelve trips a year, and the two bases give opposite answers to the same question.

Neither column is wrong. They answer different questions. If you already own the car, already insure it, and drive so little that the odometer is not what retires it, the left column is closer to what leaves your bank account. If the extra 3,240 miles a year moves you from replacing a car every ten years to every eight, the right column is closer to the truth. Write down which basis you used and why, because in six months you will not remember, and the two figures are two thousand dollars apart.

A line is missing from both columns. Twelve trips at roughly four and a half hours of additional ground time is 54 hours a year, most of it before dawn. You can price an hour or refuse to, but do not let it fall off the sheet by never being written down.

The night before is where the sheet actually breaks

This is the line that most versions of this sheet leave out, and it is usually the one that decides the answer.

A fare column, a mileage figure and a tidy net total all quietly assume you drive up in the morning. Price what an early departure actually requires instead. A 6:40 a.m. flight wants you at the terminal by about 5:30. Two hours and ten minutes of driving plus parking and the shuttle puts the alarm somewhere near a quarter to three. Do that six times and you stop doing it. You book the hotel. And the hotel is not a rounding error.

The General Services Administration publishes what the federal government will reimburse for lodging in every county in the country, which is the closest thing to a neutral published price for a room. From the per diem rates lookup, fiscal year 2026, running October 2025 through September 2026:

Nashville's cap is nearly double the standard rate for the rest of the country. That is not the GSA being generous. It is the GSA acknowledging what a room near a large-hub airport costs on a weeknight.

Put four of the twelve trips on a night-before stay at $217 and the line is $868 a year. Set that against the $556.92 that the fuel-only column showed as a gain, and the gain becomes a loss of $311. On the full-cost basis it was never close.

Then there is parking, which everybody forgets and every airport publishes. Chattanooga's airport authority lists its parking rates plainly: $10 a day in the economy lot, $12 and $15 and $20 a day in the closer lots, and $25 a day plus a one-time $1.50 transaction fee for valet. Find the same page for your candidate airport before you write anything in, and note which airport that is: in the drive-to-the-big-one scenario the lot you pay for is the large hub's, not the one down the road from you. Twelve trips of three days each is 36 parking days, and the difference between a $10 lot and a $20 lot over 36 days is $360, which is four of the airfare gaps this article started with.

Asheville beats Charlotte on three of six, which ends the rule of thumb

Run the identical procedure on a different pair and watch the conclusion invert.

Asheville is a small airport in the mountains. Charlotte is a large hub about two hours away by interstate, and the folk wisdom in western North Carolina is that you drive to Charlotte. First quarter of 2026:

Asheville is cheaper on three of the six. The average advantage to Charlotte is under eighteen dollars a trip, which does not survive contact with 240 miles of driving on any cost basis, let alone a hotel.

Compare the two pairs and the mechanism is visible. Chattanooga and Asheville are close in size, 50 markets against 49, and both are classed as small hubs. What separates them is that 53.7% of Asheville's passengers are in markets with low-cost service against Chattanooga's 13.7%. One of those airports is disciplined by a competitor and one is not. The distance from your house to the terminal is identical in both stories and explains neither.

This is also why checking the airport and checking the flight path are two separate exercises with two separate datasets. The second one, whether aircraft will be audible over your roof at 5:40 in the morning, runs on runway headings and noise contours rather than fare tables, and it is worked through in the piece on checking airport and rail noise before you buy. An airport can be cheap to fly from and loud to live under, and neither question tells you anything about the other.

Hub class is a forecast, not a fare

One more free file, and it answers something the fare tables cannot: whether the airport is gaining or losing.

The FAA sorts airports by their share of national passenger boardings, and the thresholds are statutory, at 49 U.S.C. 47102. From the FAA's own airport categories page: a large hub receives 1 percent or more of annual U.S. commercial enplanements, a medium hub 0.25 to 1.0 percent, a small hub 0.05 to 0.25 percent, and a nonhub primary less than 0.05 percent but more than 10,000. Below that, a commercial service airport needs at least 2,500 annual boardings and scheduled service, and a primary airport needs more than 10,000.

The counts behind the classes come as a spreadsheet from the FAA's passenger boarding data page. The calendar year 2025 file is still marked preliminary. Its columns give the rank, the location identifier, the hub letter, this year's enplanements, last year's, and the percentage change, which is the column that earns the download.

Chattanooga grew 13.3 percent in a year while Atlanta shrank. That does not lower this quarter's fare by a dollar, and you should not let it. What it tells you is which direction the airport is moving, which is what you want when you are signing a lease for three years rather than buying a ticket for Tuesday. Airports that add passengers add routes, and routes are what eventually bring in the discount carrier that moves the premium in Table 7.

If you need to know whether a specific nonstop exists rather than whether a market exists, that is a fourth dataset: T-100 Domestic Segment on TranStats, showing data through May 2026 when I read it. It reports, per carrier and per origin and destination pair, DepScheduled, DepPerformed, Seats and Passengers for nonstop segments. Extracting it means using the site's form-based export rather than a link you can paste, which is tedious, and it is the only place a segment-level count is published free. The fare tables will not settle this for you: a market in Table 6 can look perfectly healthy while every passenger in it changes planes somewhere else.

Eight rows your travel line needs

Everything above compresses into eight rows per candidate town. Fill them in this order, because the first row makes the rest either necessary or pointless.

Rows 2 through 7 net out to one annual dollar figure, and that figure is the travel line in the seven numbers that decide whether a move pays for itself. For the Chattanooga and Nashville comparison above, with twelve trips, the fuel-only basis and four night-before stays, it comes to roughly $311 a year against the cheaper town. Real, and small enough that it should not be the reason you pick a place. On the full-cost basis with the same four hotel nights it is about $2,300, which is large enough to matter in a comparison where the housing lines are close.

Row 1 is the one you cannot look up anywhere, and it is the one everything else multiplies by. Get it in writing at the same time you get the state approval, using the request in getting remote work state approval in writing. "Occasional travel to the head office" is not a number. Four trips a year and fourteen trips a year are the same phrase and a four-figure difference.

Start with the destination you fly to most

Do not build the whole sheet tonight. Open Table 6, filter to the current quarter, and pull one row: your single most frequent destination, from the airport nearest the town you are actually considering. Then pull the same destination from the nearest alternate airport within two hours.

If the gap is under twenty dollars, as it was for Chattanooga to Chicago and for Asheville to New York, you have just learned that this whole question does not affect your decision, and you can spend the evening on property tax instead. If the gap is over a hundred, as it was for San Francisco, keep going. Pull the other destinations, look up the two premiums in Table 7, and put the annual figure where it belongs, next to the housing line, rather than in the part of your head that stores vague misgivings about being far from an airport.

Fares, premiums and enplanement counts move every quarter. Every figure above was read on 9 September 2026 from the source linked beside it, and the calendar year 2025 FAA file is preliminary. Check the current release before you rely on any of it.
