I’ve never bought a refundable airfare. If I had to change, I paid the fee. I have never had to cancel, and if I did–most would give me a credit for a future flight. There never was a need for me to spend the extra money and buy a refundable ticket.
I had two trips (international) that were almost back to back. One to Zurich and the other to Japan. I went through Expedia and bought a multiple destination ticket. NON-refundable, because the dates were sure. I ended up not being able to go to Japan and tried to get that part of my ticket refunded by cancelling the whole trip. No go. Expedia gave me the run-around with British Airways and I am now stuck with $6000 of tickets I cannot use. I can barely even write that. Let alone SAY it.
Never again will I buy NON-refundable tickets, unless I buy them the SAME day of travel.
