What other reason is there to bail in the Main Arena?
For me it's my own "realism" or sim-like approach, opposite to a pure gaming or even airquake one. Part of the silly pretending of being a fighter pilot

.
I try to win, I try not to get shot down, I try to get home every sortie and I do at least try to save my virtual pilot's "life" by bailing. Heck, I do even bail when having no kills at all, so it doesn't gain me anything.
Bailing itself has a completely negligible influence on my score or rank. In current tour, my succesful bails just "saved" me ~5% of my scorepoints, which in turn make up only 20% of the rank calculation. Had I choosed to ride every plane to the ground, my rank wouldn't have changed at all.
Oh, and sometimes im just hanging there, enjoying the view of a big air battle. And If someone is not bailing over his own town or over a GV battle, I leave him floating in peace
