What is the movie where the women is in danger because she gets onto a plane with this man?

The movie is about this woman who is going to get onto a plane but she
has the wrong ticket or time or something and this guy gets onto the
plane and tells her something like everything happens for a reason or
something like that and the woman somehow got her ticket changed and
ended up on that plane with the man and the man sits with her and they
talk and drink and stuff. Well then the man gets attacked while the
woman is in the bathroom and saves himself and the woman but then he
has to either kill or knock out the pilots so he has to fly the plane
and that is when the woman figures out she is in danger also.

Also in the movie the man puts the woman to sleep many times so she
wont get hurt and the man ends up taking both of them to this island
while she is still asleep and while she is still asleep she changes
him into a bathing suit and he says something like with my training im
capable of changing you without looking.

I know that I know a lot about this movie and its because I have
already seen it but I would like to watch it again i just forget what
its called. If you know the title of this movie please leave an
answer....Thanks!!
