If I purchase a ticket using my credit and can not make the flight what happens to my credit If I purchase my ticket using my credit and can not make the flight what happens to my credit? When I try to select seats it says unavailable even though I paid for it I wanted to know where is writing on terms&conditions when we have a travelcredit we can't booking a flight online and we have topaymoreforthat?! I wanted to know where in the terms and conditions is writing when you have a travel credit you can't booking flight on line and haveto paymorefor it? My wife needed to rebook due ot emergency surgery. Just Fly will not communicate with us. Why not? So if your staff is the one that makes an error in the booking, who pays for the correction just curious if I will receive confirmation on my flights via email after booking? can i get a refund because justfly and china eastern would not help me rebook because of a typhoon I booked the flight, but why there's no place to fill my password information ? is it right?
