Can't move air units

[Bella]

I'm playing as Allies in the campaign game of BTR. Try to move air units, and it allows me to select the unit, but won't transfer to the airbase I select. I was able to transfer units in Eagle Day scenario as German, so it's not about me not knowing the right steps. Anyone know a solution?

Allied units can only be transferred between airfields within the same command.

This is by design, to represent the policy decisions coming from on high, and to prevent stacking one command/theater with all the goods...
