Finally booked my 1st trip - Dec17/Dec18: BUF-PHL-LGA//LGA-PHL-BUF for $291.88... then discount to $0
Just tried to booked my 2nd trip and can't applied the COUPON with the following error:
We're sorry, but our records show that this voucher has already been used.
and I haven't enter anything credit card info yet.
Anyone else have this problem?
