Maybe, but Indepedence Air went overboard with their expansion [borderline explosive expansion in my book] and in just mere two years they flew to 37 destinations with over 200 daily departures. VX is not even close and they have been running for almost 7 years now.

I don't think F9 is going to make the same mistake and they are much more established/known than I-Air.

I did a trip with them once [SFO-IAD r/t] and it was a decent airline.
