It is close: flying saves about 2 hr 13 min of travel time, but driving saves roughly $51. Either can be the right call.
The honest answer to “Los Angeles to Phoenix: drive or fly?” depends less on the flight time than on everything around it. A nonstop is only about 1 hr 9 min in the air, but getting to the airport, clearing security, boarding, and reaching your destination at the other end realistically adds around four hours. That pushes the true door-to-door flight time to about 5 hr 9 min, against roughly 7 hr 22 min for the drive.
On cost, a solo driver burns about $54 in fuel each way, while a one-way ticket runs near $105 per person. Driving’s big advantage is that the cost is fixed per car, not per head — so the more people travel together, the more the maths tilts toward the road. On fuel alone, driving comes in cheaper than flying here even for a solo traveler. The table below shows how that plays out.
How the maths changes with your group
| Who is travelling | Drive (fuel, 1 car) | Fly (airfare) | Cheaper |
|---|---|---|---|
| Solo, one way | $54 | $105 | 🚗 Drive |
| 2 travelers, round trip | $109 | $420 | 🚗 Drive |
| 4 travelers, round trip | $109 | $840 | 🚗 Drive |
