Here they are, compiled by a good guy with plenty of patience, that is for sure.
Of course, the fees change almost daily so check back with him to see what is up.
It's useful, but doesn't take into account high-elite flyers. I don't have to pay any change fees for cancellations of FF tickets on Delta and all taxes are refunded (as long as it isn't made within 72 hours of the flight). I've changed my flight for this week four times! (But now I can't after today, not that I was planning to ) I also have free skypriority boarding, free checked bags, etc.
anadyr, another great article! This is a very helpful side-by-side comparison of all "extra" airline fees.
