Too much mistakes, too less story.. I was watching this movie together with my wife, where she was keen on watching, while I was more interested in somehow spending my time.
Because I'm German based and she is not, the starting of the movie promised quite an interesting movie for me, since they used real German sentences in it, even Jodie Foster spoke her few words quite well.
The starting pictures are really well, but as soon as they go on the airplane the movie gets boring. And when I say boring, I mean so. I was searching a logical storyline, or even a storyline to speak of. Sorry, no success in finding one. The plane might be interesting as a technical design, but all those flaws... WHY will the flight marshal get her daughter alive? Why not just kill her in the plane where he left her? Besides that, a whole plan just on the matter that no-one will remember her daughter, even when there are many other people in the plane? How did he got her away, anyway? I'm a frequent flyer, and I can tell that usually there won't be that many people sleeping in the first 2 hours of a intercontinental flight, most basically just wait for food. And in a brand-new airplane, there will be a lot of people anyway who try out all the new games/movies they find at their seats...
Another question, why does she travel Economy Class? Or is the comfort in Business that worse in her new airplane? If she is really having a decent job, why in Jesus name is she not flying business? Too many mistakes in the story, not to talk about that it can't be true that no person even noticed when the guy got the girl somewhere down in the airplane.. either this plane has some secret elevator which can be used comfortably, or it's just plain huge holes in the whole story.
Anyway, the basic idea is nice, the plane looks well inside (give you a guess how it could be in the new airbus, as soon it's ready for regular flights) and some parts are seen for itself quite well, so I'm still giving it a 3 out of 10.
Worth having a look on TV or if you get the DVD for cheap, but not a movie you should go for theater or get on DVD when it's fresh out.
