33% cancellation fee in my case. My in-laws who are in there mid 80"s had a medical emergency and couldn’t fly up from Florida. There are no conditional reasons for cancellation acceptable to JetBlue.
Be very sure you are staying healthy prior to your trip.
If you purchase a $100 ticket you lose 100% of the purchase regardless of the circumstances. What's next from the airlines?
Perhaps a charge for sitting in the boarding area.
How about charging for leg room, oh they do that already. Maybe you have to purchase a key to put your luggage in the overhead.
I don't want to give them any ideas.
