I recently flew SJC-LIH on Alaska but purchased the tickets from American Airlines (they were cheaper than AS). Upon check in the agent charged $25 for checked bags instead of the usual $20. AS metal, AS Mileage Plan number on the account (I currently don't have elite status). I reviewed the Alaska webpage and found no mention of having to pay an extra $5 because I ticketed with another airline and am now starting to think I was overcharged/ripped off. I noticed bag fees are increasing to $25 but that does not take effect until October. Curious if anyone else has anyone else had this experience?
