NOTES:
(*) SWQ (Swift Air) numbers charter flights sequentially in the same series; flight number listed is the most recent which I was able to confirm.
(**) ACA (Air Canada) has a contract with the NHL to provide charter flights for the seven Canadian teams (similar to the NBA/DAL deal). All ACA NHL related flights have been using A319s.
Also worth noting that the NHL teams which charter with DAL (except for Anaheim and Buffalo) share an arena with an NBA team, so it’s possible that those particular charters are being coordinated with the NBA teams or in some other fashion. I’m guessing that’s the case because all of the NHL related DAL charters are using B752s.
EDIT: 1538 EST, 11/6/17 Updated to include Dallas, Florida, New Jersey, New York Islanders, Tampa Bay and Vegas. 0210 EST, 11/8/17 Updated Dallas Stars to reflect probable GTI flight number.
