Best Airline for DEN-LAX UM Flights
For Ages 5-11: Southwest
Southwest is the clear winner for younger kids:
- Lowest UM fee at $100/way ($200 round trip)
- Multiple nonstop flights daily
- No change fees if plans change
- Free checked bags (2 per person)
Limitation: Southwest doesn't accept UMs ages 12+. Kids 12-17 fly as "Young Travelers" with no special service.
For Ages 12-14: United or Delta
Since Southwest doesn't offer UM service for 12+, choose United or Delta:
- United has DEN as a major hub = most flight options
- Delta offers Sky Zone lounges for UM waiting
- Both are $150/way
