Driving comes out ahead — roughly $50 cheaper, in similar time.
The honest answer to “Los Angeles to Las Vegas: drive or fly?” depends less on the flight time than on everything around it. A nonstop is only about 55 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 4 hr 55 min, against roughly 4 hr 59 min for the drive.
On cost, a solo driver burns about $35 in fuel each way, while a one-way ticket runs near $85per 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. The table below shows how that plays out.

| 4 travelers, round trip | $70 | $680 | 🚗 Drive |
