Qantas flight model (pls help)?

I don't think it's going to be a 747 you're traveling on. Those are usually used for long flights with a big number of pengers. For a two-hour flight most likely it's going to be the 737 and from the photos it is a 737. This is the smallest boeing . I like to sit right behing the wings so I can watch the flaps when they move up and down, or just in front of the wings so I can watch the engines.
