Not sure where else to put this:

American Airlines has ended its charter flight deals with the Cardinals, Ravens, Colts, Jags, Dolphins and Steelers, citing inadequate machinery. Up to 20 teams don't have a charter provider for next season (not sure if said six were included in that count).
I'd kinda like to see United try to drag Brandon Williams off a flight though.
