It now costs $200 to change or cancel a non-refundable airfare on the remaining "legacy" U.S. airlines (American, Delta, United, and US Airways), and a bit less on some other airlines. But there are ways of avoiding the fee.
Airfares are higher than they've been in years, but there's some good news: airlines are at least putting your money to good use, buying new planes with the latest in-flight entertainment systems, seats that maximize knee-room if not hip room, and inflight connectivity.
Airlines: Stop forcing that default complimentary soda and snack on your economy passengers on domestic flights. Most of us don't want it, all of us can do without it and we all know you can't really afford it.
Airline passengers hate all those extra fees for bags and flight changes, and according to my emails and Twitter feed, many would like the extra perks to be "re-bundled" into fares (i.e., stop "nickel and diming us").
