The Best Budget Airlines Flying Out of LAX in 2026

From Southwest to Spirit, here's a complete breakdown of which budget carriers offer the best value from Los Angeles.

Best Budget Airlines from LAX in 2026

LAX is served by every major US carrier plus dozens of international airlines. Here's how the budget options stack up.

Southwest Airlines

**Best for**: Domestic routes, bag-friendly travelers

Southwest doesn't charge for the first two checked bags — a $35-70 savings per trip. Their no-change-fee policy makes them ideal if your plans might shift.

**Typical savings vs legacy carriers**: 15-35% on domestic routes

Spirit Airlines

**Best for**: Price-conscious travelers who pack light

Spirit's base fares are often the cheapest available, but fees add up fast. A carry-on bag can cost $45+ if not purchased in advance. Pack a personal item only to maximize savings.

**Key routes**: LAX-LAS, LAX-ORD, LAX-DFW

Frontier Airlines

**Best for**: Budget routes with frequent sales

Frontier's "Den$e" sales can drop prices to $20-29 one-way. Subscribe to their deal alerts alongside ours.

Allegiant Air

**Best for**: Nonstop service to leisure destinations

Allegiant flies routes that legacy carriers don't — smaller leisure markets with nonstop service from LAX. Good for vacation destinations like Palm Springs, Provo, or Destin.

Which Airline Should You Choose?

Our recommendation: compare total cost including fees. A $150 Spirit fare with $89 in bag fees loses to a $185 Southwest fare with free bags.
