Compare all airline fees (U.S. airlines only) with this simple tool
An awesome new tool by NerdWallet lets you calculate and compare the fees that different airlines (in the U.S.) charge for cabin and checked bags, rebooking, or unaccompanied minor tickets. This makes it easier to compare airfares that might seem cheap before you start piling on fees.
For example, if you’re checking and carrying one bag each, and have booked your round-trip ticket online but want to print your boarding pass at the airport. These options will cost you an extra $200 on Spirit Airlines, but JetBlue and Southwest charge zero fees for any of them.
