Since this Envoy fanboy is still posting in here.... If it goes to the cheapest bidder, that won't be Envoy. So make up your mind is it going in house where they're throwing bonuses around or is it going to the cheapest bidder. News flash, we're lower cost to AA than Envoy. So although Mesa is cheap AF, their performance is crap, even Uncle Doug (Doug Parker) sees the value in not giving all of the flying Compass is doing to Mesa.
If it all went back in house there would be no way to tell you that Mesa or Compass are doing it cheaper the next time your contract is up for renegotiation. Uncle Doug ain't stupid.
