I realize that some of you might say it is just the winglet that looks alike, but put grey where green is and blue where white is and it's US Airways all the way. Looks like they even copy on the other side of the world.
Yes, there are some similarities, but, in all honesty, how many variations on the cheatline can one have? I'd be a bit more inclined to agree if the tail stripes were similar. Still, it is an interesting idea you brought up.
