Rebasing bombers

[Barhoumi]

Why I often can't rebase my aircrafts into some cities or carriers?
And thank you

I believe the you can only rebase your aircraft to cities or carriers that are within twice its range, so that's probably why.

Or maybe you have exceeded the limit that the city/ carrier can have.
