Long story - I was meant to fly PER-SEA transferring in SYD-HNL. First two legs QF, final AS. The SYD-HNL was delayed so QF, while I was on the flight and unknown to me, reissued my ticket to go to SEA on United Airways on Tuesday.

As I landed in HNL, I saw the AS flight was delayed and hadn't left yet. So I ran (literally) to the AS checkin desk given there were only a few mins remaining. They saw that my bags were tagged through to SEA and that I had a boarding pass and sent them through. When I got to the gate they wouldn't let me board as they scanned my boarding pass and said my ticket was no longer with the airline (which was right, but I didn't realise as I wasn't informed by QF).

But my bags were loaded onto that AS flight, and made it to Seattle. AS in HNL said I can just pick it up from SEA when I finally get there, but they seemed fairly clueless and didn't want to take any info from me. They also said they can't track the bags using the QF tracking code, but know it went because they did call HNL baggage who said all bags were loaded and nothing was left behind. An AirTag I had in one confirms it travelled.

Though I don't know if I should do anything more. I thought about lodging a baggage claim, so they know someone's coming for it. QF said I need to do it with AS, as they handled the last leg. AS said it's a QF baggage tag/code and so they can't 'look it up', and QF need to do it. So I don't know how to start - and QF's customer service centre is unbelievable bad at understanding any issue.

My worry is that since I won't fly Alaska at all, they won't have any record of me so they might just think it abandoned? I.e. it's not like I'm on an Alaska flight in a few days, but rather United.
But also, I wonder if I try and start some delayed/lost process, it will make more problems than just picking it up when I arrive? I definitely don't want them to think it's unclaimed and send it elsewhere.

Any thoughts welcome! Thanks

Edit: Not sure if this is the best forum for this, but it is about how to navigate AS.

Why are you not taking your final HNL-SEA flight on United for a a few days? Regardless, your baggage will be in SEA at the Alaska baggage office once you did not pick it up from the carousel.

Pretty sure 48 hours is totally routine for separated baggage; I wouldn't worry about it being destroyed. Any human looking at the bag tag will see that it was issued by QF and not be surprised that there's no record of you. I don't know if it's possible to actually get on the phone with a human in the SEA baggage office, but once you get to two hours after the arrival of the HNL-SEA flight your bag was on, I'd try that and just tell them to hold it for you.

Aside: these automated pro-active rebookings when you haven't actually missed your connecting flight drive me mad. In this case, it may be reasonably legitimate since your delayed flight was likely scheduled to arrive after your HNL-SEA flight was scheduled to depart, but stuff happens. Not being able to get on your originally-scheduled flight when you did in fact make it to the gate in time is maddening. I get that often it is nice to rebook you off impossible bookings, but doing so without your consent when there was still a chance that a delay of the connecting flight (not unusual!) would make it possible to make the connection is not what I typically want.

And I would definitely try to get on a flight sooner than Tuesday (unless you're happy to enjoy an unscheduled day on the island!). I don't know how standby would work on UA or AS given that it's a QF ticket, but having to wait two days seems nuts even if there's no current availability.
