Why should anyone gimp themselves because YOU took your time leveling? If the current plans go through, it is very possible that people will have classic flight unlocked on day ONE, II said a few days cause I know not everyone speeds through the content.
The only way you are at a disadvantage is because YOU put yourself at one. If anyone in your family can handle dynamic flight, maybe play wit them and have them taxi you around, or find a friend willing to do so. Maybe just buckle down and do the content and get the flight you want possibly on day ONE.
