Being 27 - time to command is not an issue
I know time to command is always a rather 'fluid' figure but I am a similar age to you Jinkster and I have ruled Virgin out because of the potential time to command. The length of time has steadily got longer with time and circa 15 years could be quite possible! Granted it could shift either way yet it is still going to be a very long time for what is still a rather small company in terms of fleet size.
It all depends on what you want and perhaps the fact that I would be giving up a jet command in the process might be clouding my judgement slightly!
