You are right, would be more realistic, and has been discussed many times, but it would not match the other relations in this game.

If you were to double the range for relocation purposes, even ints level 1 could already reach airports that would currently only be accessible at level 6, and for bombers even farer airports would be reachable, from which the planes then might attack in their usual range.

That on one hand saves a lot of airports (or carriers) respectively the cost of their construction and the respective time required for refueling there, and, beyond and much more serious, even planes on low levels and already in the early game might be able to reach provinces far away (on the 22p map eg beyond the Mediterranean, the Baltic or other seas, or beyond other countries) for which they should not be able to do due to their level and the general progress in the game.

All that would mean a massive intervention in the game balance (in favor of the planes) especially of early maps (it would cancel the "time-brake"), because, while everything around is still on a low level, e.g. planes at level 1 would have a mobility as level 6 planes has now.
