I recommend the Retina Pro to almost anyone. The battery life is still great (8+ hours with light use), and the screen is phenomenal. You also get a bit beefier performance.
The Air does have fantastic battery life (12+ hours), as well as slightly better portability, but not drastically. The Pro weighs about half a pound more.
You won't be disappointed with either one, I'm sure. If you think there's any chance you'll do some photo editing, or just general movie watching on it, I'd recommend the Pro for its screen any day of the week. If it's gotta make it across an international flight with no plug, grab the Air.
