hello. Hopefully this isn’t too far off topic but I couldn’t find another thread and wasn’t sure if it was appropriate to start a new one since my question is related to upgrades. I followed the steps that I found on google and it didn’t work for me. Would someone help me determine if a flight has availability for SWU. I’m flying flight 34 on 1/30/26 from AKL to DFW. Where do I look when booking the flight? Can I see it if I use the app?

Thanks in advance.
