1) I used the NCAA's definition of a flight (a trip greater than 350 miles) and I based my mileage on Google Maps.
2) Obviously, this methodology is incapable of distinguishing "practically in-state," like Manchester, NH or Providence, RI for MA teams, nor can it separate out really long cross-country flights vs. shorter, quicker flights. But it's a decent start.
3) All records are based on the regional rounds; I did not look at the Frozen Four.
To the data:
Overall 2008 - 2015:
Teams playing in-state are 25-15
Teams traveling out of state by bus are 23-15
Teams flying are 39-54
1 seeds are 9-1 in state, 15-3 by bus, 7-10 by flight
2 seeds are 9-9 in state, 0-3 by bus, 9-12 by flight
3 seeds are 4-3 in state, 8-8 by bus, 7-14 by flight
4 seeds are 3-2 in state, 0-1 by bus, 15-18 by flight
