Quote from Axl in hecks on a plane
Axl: I can't believe I got bumped up to first class. Sweet! Sue: You didn't get the upgrade! If anyone got the upgrade, it's me. Axl: Pfft. Please. Just being allowed to travel with the humans is an upgrade for you. I thought they were gonna make us check you with the rest of the pets. [chuckles] Oh, yeah! Ax-man's already swinging at 8:00 A.M. Mike: Cool it, Ax-man. Everyone will get their chance in first class.
