This was the 1st time I flew with Frontier and this will be my last guaranteed. Yes, I will recommend this airlines, ONLY to my enemies. They gave us boarding passes (4 passengers, my wife, myself, daughter-12yrs, son-2yrs) all 4 seats together in one row (36 C, D, E, F) and we were waiting at the gate then they called us to tell that our seats are now all scattered in 4 different rows. We just couldn't believe, how was that possible!!! We have our boarding passes, 10 minutes to boarding and now they are saying we have different seats! Our 12 yr old daughter and 2 yr old son will be seating in different rows! I initially thought it was a joke but then I realized they actually sold our seats to others. What a cruel dishonest American corporation! I must say another point, their luggage weight restriction is 40 LBs whereas most of the airlines is 50 LBs. So, please don't be tempted by their initial cheap fare offer, ultimately you will pay more and suffer more.
