Texas Tech does not fly Continental. They fly on a Southwest charter. I know a coach at Tech and I asked him. At least for the football team. As for the basketball team, they use different carriers, but they MUST all fly in a jet aircraft. This is mainly due to the tragic plane crash a few years ago of a Beechcraft King Air that was carrying some of the Oklahoma State Cowboys baskeball team back from Colorado to Stillwater, Oklahoma. All on board perished.
As for the Texas Rangers baseball team, they just got their own 727 and it is parked at Dallas Love Field. I don't know if the Dallas Stars will use the same plane, since the owner of both teams is the same man, Tom Hicks.
The Cowboys used to fly Braniff and now they fly AA
Ryan International is a larger sports charter operator and they have taken to painting their planes in the old and last Braniff "ultra scheme" but without the Braniff titles on the front. They have even given them "N" numbers that end with BN
I think the Oakland Raiders will be flying into DFW
next week on a Hawaiian Airlines 767 to play the Cowboys. Josh and I are going to try and get photos of it.
