Well, there are a couple of points to take away here.
#1 We don't "FIM" pax over to other airlines because when you buy a ticket on Jetblue it's "money up front" so to speak. We don't over sell flights and when you buy a ticket you really do get that seat. What a novel idea if you ask me. Now, you can change the reservation for a nominal fee, but the seat is yours to lose.
#2 The refunds you talk about ($156) where what they paid for the ticket? As far as having to buy a ticket on another carrier for $700, Well they are legally getting raped. Take a look at our "Walk up Fares" we don't stick it to someone when we certainly could.
So, tell me how JetBlue wants to hold you captive?
