i have no idea what this movie is help

so there's this very graphic movie i vaguely remember seeing when i was very young, i have no idea how because my parents were pretty strict about what i could watch, but i know i saw it and it traumatized me.

here's the only scene i can remember: a guy (detail: he's very overweight) is on a plane. a mother and her daughter are sitting next to, behind or in front of him (can't really remember). he feels sick and, this part is a bit fuzzy, i think he wants to get up to go to the bathroom but can't unbuckle his seat belt. one way or another he ends up throwing up on the mother and her daughter, and his vomit is full of worms/bugs. his body ends up being torn apart by more worms/bugs that keeps coming out of him. and that's about it. i could tell you more things like i'm pretty sure the guy wore a blue shirt, or that a flight attendant spoke to him when he was starting to feel sick, but i don't know if those details were made up by my brain or if they're really in the movie. but yeah that's really all i can remember.
