last time I flew they had a little cart with chips, candies, and drinks that the attendant pushed around a few times.
also had a mini bar, but it was waaaaay over priced, like $10 for a little shooter of jack daniels. I got 3 lol.
Pretzels and crackers are more of a thing on airlines. I hear it's because it's cheaper to make in comparison to peanuts, but that's from a friend who works at Boeing.
