Alaska Airlines has been quietly warning passengers for years that it charges $25 for every oversized carry-on it has to check at the gate.
The airline says it has actually had to charge the fee on occasion lately. But contrary to some media reports, it isn't considering setting up a cash register at the gate.
Spokeswoman Marianne Lindsey says customer education and promotion of the $25 fee has taken care of most problems concerning oversized bags and extra luggage people are trying to place into overhead bins.
Lindsey believes the Seattle-based airline's carry-on rules are similar to other carriers. The Alaska Air fee differs significantly from new fees at Allegiant Air and Spirit Airlines. Those airlines are charging for anything that goes in the overhead bin.
