Drive or Fly for the Holidays: At 1,200 Miles, Driving Wins From 2 Travelers at a $400 Fare, From 3 at $200
The “drive or fly” debate usually starts with distance, but the bigger variable is who’s in the car. A car costs the same per mile whether one person or five are in it. Plane tickets multiply.
We ran holiday trips through the Drive or Fly calculator with this week’s gas price, EIA’s U.S. average for regular at $4.284 (week of October 19, 2026), a 28 mpg car, and AAA’s 2026 Your Driving Costs averages: 11.73¢ a mile for maintenance, repairs and tires, plus 8.38¢ for the extra depreciation (AAA’s $419 difference between 15,000 and 20,000 miles a year). All in, 35.4¢ a mile. The flying side uses example values: one checked bag each at $40 each way, $80 for airport parking or rides, and a rental car at $60 a day for 5 days. Drives longer than 10 hours a day get a $150 hotel night.
The group size where driving wins
The fare is the input you can’t guess, so we varied it. Each cell is the smallest group for which driving is cheaper than flying:
| Round-trip fare per person | 800 miles one way | 1,200 miles | 2,000 miles |
|---|---|---|---|
| $200 | 2 | 3 | 8 |
| $300 | 2 | 3 | 6 |
| $400 | 2 | 2 | 5 |
| $600 | 1 | 2 | 3 |
At 800 and 1,200 miles, a couple already saves by driving at almost any fare. At 2,000 miles the drive takes three nights on the road each way, $900 of hotels, and flying stays cheaper for groups of up to 2 to 7 people, depending on the fare.
Below 800 miles, the table isn’t interesting: at 500 miles even a solo traveler pays $394 to drive against $860 to fly.
Why the gas price barely matters
Gas prices vary by about $1.77 a gallon across the country this week. EIA has the Gulf Coast at $3.784 and the West Coast at $5.557. Here’s what that does to the round trip:
| Gas price | 500 miles one way | 1,200 miles one way |
|---|---|---|
| $3.78 (Gulf Coast) | $376 | $1,147 |
| $4.28 (U.S. average) | $394 | $1,190 |
| $5.56 (West Coast) | $440 | $1,299 |
The swing is $64 for a 500-mile trip and $152 for 1,200 miles, less than one plane ticket. Fuel is under half of the per-mile cost once maintenance and depreciation are counted, and those don’t change with the pump price. If you’re comparing, spend your time on fares and bag fees, not on gas.
The time side
Money isn’t the only thing. For the family of four, flying saves 7.7 hours round trip at 500 miles one way and costs $1,906 more, $249 for each hour saved. At 1,200 miles it saves 28 hours for $1,110 more, $39 an hour. That’s the number to weigh against what a vacation day is worth to you, or against the real hourly rate you’d earn if the extra days were workdays.
Short trips flip the other way. At 300 miles, airport time (we use 3 hours per leg) eats nearly all of the flight’s speed: 4.1 hours door to door against 5 hours of driving.
Where this doesn’t apply
- Connections. The flight time assumes a nonstop. A connection adds hours and often a higher fare.
- Renting the car for the drive. Without your own car, swap AAA’s per-mile costs for the rental’s daily rate plus gas.
- Holiday traffic. Thanksgiving week highways can run well below 60 mph. Lower the average speed and the hotel nights may change.
- One exhausted driver. If only one adult drives, 10 hours a day is a lot. Fewer hours per day adds hotel nights.
- Wear you won’t feel. Leaving depreciation in assumes the miles reduce what the car is worth. If you’ll drive it until it dies, you can switch it off and drop 8.38¢ a mile.
What to actually do
- Price the actual fares for your dates, including bag fees for your fare class.
- Enter your group, distance, mpg and local gas price in the calculator.
- Check the cost per hour saved, not only the cheaper total.
- For a drive over 10 hours, decide the overnight stop up front and include it.
- Before booking anything nonrefundable, see when trip cancellation insurance pays off, and for what your car really costs per year, the true cost of car ownership.
Quick answers
Is it cheaper to drive or fly for a family of four?
Usually drive. At $4.28 gas, a 28 mpg car and AAA's 2026 per-mile costs (35.4¢ a mile including wear and depreciation), a 500-mile trip costs $394 round trip to drive against $2,300 to fly at a $400 fare with one checked bag each and a 5-day rental car. Flying only won for four at 2,000 miles, by $56, after three hotel nights each way.
How many travelers does it take for driving to be cheaper?
At 1,200 miles one way: 2 travelers at a $400 or $600 round-trip fare, 3 at $200 or $300. At 2,000 miles: 3 travelers at $600, 5 at $400, 6 at $300 and 8 at $200. At 800 miles driving wins from 2 travelers at fares from $200 to $400 and even for 1 traveler at $600.
How much does the gas price change the answer?
Less than people expect. For a 500-mile trip, round-trip driving cost goes from $376 at the Gulf Coast's $3.78 to $440 at the West Coast's $5.56 (EIA, week of October 19, 2026). A single plane ticket moves the total more than that.
What does each hour saved by flying cost?
For a family of four in our example, $249 an hour at 500 miles one way, $85 an hour at 800 miles and $39 an hour at 1,200 miles. Below roughly 300 miles flying barely saves time once you add 3 hours at the airports per leg.
