Movie help!

I can remember watching a movie where a man is flying to his sisters wedding and meets a woman on the flight. The flight is taking off but a bird flies into the engine so they have to evacuate. 
I’m sure they stay together as they become friends, there’s a scene where they’re in a night out and bump into a hen party and a scene where it’s pouring rain and they run into a supermarket. 
the movie cover has a turquoise rain like background with two people floating falling into each other. 
maybe around 2005? Someone please help!
