These are very good attempts - well done.
Given the motives of the photos I would suggest sizing at 1024, as that will maximise the look of the quality. Also, on the first, does the original allow you to extend the crop very slightly on the right so that the flap fairing is not cut? But that one is a good one.
I think the last shot is the best of the Easyjets, personally, and it looks like you need to be careful of a bit of grain. For example, in 'AA', it looks just a bit grainy under the wing area. Ian is correct - they will get rejected for dirt, if nothing else. All three Easyjets have significant dust spots that you can see with the naked eye.
