Well, I am curious, how do bombers gain experience points beyond the initial points for airports, theocracy, wonders, and military trainers. I have them on constant bombing runs of both units and improvements/cities, yet none of them get promotions. I don't even notice them getting experience points for surviving being intercepted. It is very frustrating because I think a bomber that survives a bombing run in enemy territory that is filled with fighters, SAMs and other traps for them should get experience points.
You only get experience points when you manage to kill stuff. So a bomber that kills a fighter which tries to intercept could get a promotion, but that's the only way that it could happen (I think).
It's clear that it would be very rare for bombers to get experience. On the other hand, there aren't many useful promotions for bombers either. The promotion that helps with evasion might help. If you want that promotion, then it's best to build your bombers in a city that produces very experienced units so that you can pick it from the start.
It's hard to come up with a meaningful way to give experience to bombers without making it too easy to get experience for these units.
