I am absolutely addicted to this game, and have not grown bored of it for the entire time I've been playing, which has been years now. Basically no mtx other than buying the in-game currency bux that you can get easily by playing, and watching very generous ads that are optional. It's not quite my favorite airline game ever, which was Aerobiz Supersonic on the SNES, and there's certainly things id love to see added, but overall I love this.
