I received a fly card for a gift and wondered why I can’t redeem it now. It has been a couple of years since I received it

They don't expire. I had one for 3yrs before I used it.

Michelle, the flight vouchers shouldn't expire. Call the local iFLY and they should get you sorted. Some of the vouchers use characters that are difficult to distinguish (for example, two underscores in a row) and it's possible the code wasn't entered correctly. Another thing I'll warn about is posting a picture of the code publicly, as anybody who has the code can redeem it via the internet.

Yes you can I got mine from my brother, and I think it has set date to use it by. Also real skydiving is way better than ifly for about the same price
