Alaska Airlines has direct flights from SeaTac to:
Eugene
Burbank
LAX
Omaha
M-StP
Milwaukee
O’Hare
Des Moines
Indianapolis
Detroit
Columbus
Baltimore
Newark
Pittsburgh
So direct flights within a two hour drive of every BIG team except Penn State, which is 2.5 hours from PIT and not much further away from BWI.
Alaska Airlines can stay.
Except that there aren’t many of those flights.
You’ll be left with one or 2 stops on American Airlines fighting with a ticket agent to get on a plane, any plane.
Clearly you haven’t flown much lately.
