This thread needed a full refresh, as someone who has been trying to treat myself to a few AONE tickets, I’ve taken the time to (as at January 2025) put together my current understanding of the remaining First class routes.

It is surprisingly hard to find these routes as, except for BA and their low fare finder, and generally it seems that the knowledge is hidden amongst various websites (prince of travel is particularly helpful), news articles and so forth. I tried to use ExpertFlyer to validate any potential routes that were listed - but would welcome any new ones. As a result of this work I am going to try and layer in a KUL-Tokyo flight to end my next AONE3 as JL seems to refuse releasing any first class seats anymore.
