^ Well the first line of the chorus has the same vocal melody, but that's it. Very brief similarity.
Airplane is actually a weird track for me, coz I kind of really like it, but some parts of it get kind of irritating to me, like the speaking bits and especially the repetitive part leading into it and whatnot, but everything about the chorus and verses is pretty great, not to mention the bgm. In that live it's even hard to hear shit properly coz fans just don't know when to shut up (hint: always).

Man, Luna in these perfs, Jesus fuck I didn't expect to have this many feels. She's stealing all my attention. I just love her outfits, those pants in airplane, ohh man.
