I think what he/she means is the livery that on a certain type of plane that is different from the carriers standard livery while it still not considered a very strict subcategory of special livery (as it applies to many/most or even all of the aircraft type) the case like that I knew is Sichuan Airlines A359 and China Southern B788/B789.
ANA A388 is also the case but you don’t have access to that in the game via normal contract.
oooh right thanks everyone. LeChonk I was thinking more outside of the passes as I’m trying to save my gold coins, but it seems like IAD has some interesting liveries so I might need to use my coins after all…
Dreamliner thanks for the info on Sichuan, I’m guessing this is a Sichuan specific thing.
You can also get the SkyMarks Pokemon livery as a permanent contract at NGO, or at least you used to be able to. I kept mine, so it’s funny to see it also as an event sometimes.
