Thanks everybody, for the information!
Since I have only 2 characters currently and neither of them has hit 20, I'll just wait and take it as a second travel power, that way I don't have to spend anything. At least, if I understand what you guys are telling me!
Disappointing I can't just slot it right away but I'm not that anxious as to use the free retcon I still have, so I'll have rainbow flight as a perk for when I level up a little.
I feel much less frusted just knowing the information you guys gave me. I couldn't find it stated plainly anywhere, whether my search fu is just bad, or it isn't there.
CoH community wins again!
