Alaska Airlines To Charge Upgraded Passengers Bag Fee

Alaska Airlines will become the first American airline to charge a checked bag fee for first class passengers, reports CNBC.

While passengers with full-fare first class tickets will still fly fee-free, beginning in July, passengers who upgrade will pay $20 each for their first and second checked bags.

According to Alaska's website, first class upgrade passengers who were confirmed on or before May 15 will not have to pay the new fee. Those who were confirmed on or after May 16 will pay the $20 as of July 10.

Airlines' fees have been making headlines for a while now. Carry-on fees, which Alaska charges, and charges to print boarding passes are just two examples of the hidden costs that have many travelers up in arms.
