Well.... I have to tell you. I cancelled my flights and re-booked.
Not only did I have no problem -- I am getting a refund (to my credit card of approximatley $100 Canadian (flights are lower than I originally booked), and I have a $12 credit that I must use for another flight.
I am delighted.
Sooooo........ for $500 US the four of us will fly from Buffalo to Orlando and back. I could just scream I am so excited !!! and to think I really had hope to JUST change the date.
