When checking in with AS at LAX, gate agent wanted to charge me for the 55 lbs bag. I showed her the baggage allowance on the e-ticket, and she didn’t care. I was going to ask for supervisor but decided to just comply and move things around since I was tired from jetlag. After I opened my cases and started spreading things in front of her counter, she decided to take pity of me and give me a one-time exception.
This is a misconception on ticket stock. The bag rules are filed with ATPCO based on the *fare rule* of the fare purchased. We (travel agents) can plate (or issue a ticket) on any airline we wish, as long as there is a valid interline agreement. But that doesn't automatically apply that baggage rule of that airline to the operating carrier.
So when you were flying on CX HKG-SEA, if it was on a JOINT FARE/THRU FARE (meaning the same fare code/class of service all the way thru), then YES, the higher allowance on CX first would apply.
The other misnomer with interline is how airlines handle overweight and excess fees. Some airlines (like DELTA) are very strict and stringy with it. Others do what is called "Collect and Carry". So when you fly Alaska Airlines to Honolulu, and connect on Hawaiian to Maui - Alaska will allegedly "collect" the Hawaiian bag fee of $25 and get to keep it, as Hawaiian is expected to do the same on the return. If Alaska doesn't charge the fee and your bag goes all the way thru to OGG, then good for you and you got an agent not following the rules
In the case of Delta, Delta would collect the $25 from Alaska by the form of an EMD - Electronic Miscellaneous Document (MCO) - and is handled like an interline ticket. Delta also has a new blocker, where if it doesn't see a bag fee charged on an interline ticket (or waiver), you can't check-in and have to pay the fee before you get to board.
