My husband and I were absolutely sick about the flight prices from LAX to PIT during the holidays. When I found a flight from LAS to PIT for at least $1,000 less, we decided making the journey in the car was worth saving.
We were both concerned about leg room and flight delays. What a pleasant surprise when we actually departed early (with everyone boarded, of course) with less time in the air than anticipated. The leg room wasn't really a problem (even for my 6'4" husband) because the seats aren't padded, so you gain leg room from that.
We also checked one bag to save money (instead of paying for two carry-on's) and that came very quickly after we got to baggage.
Overall, for the price it was a pleasant experience. Thanks Frontier!
