you dont have to be middle eastern. but i think of it like this: if American Airlines sponsored a team in lets say Iceland. the icelandic population here is small. they're better off getting with an icelandic airline.I'm not sure why you think you need to be Middle Eastern to fly Etihad - Middle Eastern people are only a tiny percentage of the people who fly Etihad; I think Etihad is already the major airline flying out of several major cities (including Manchester and Melbourne, for the record).
Also, about Etihad and JetBlue having a partnership:
