Did Palin bill Alaska for all of the travel or part of the travel? Did the state pay for both Palins or just the Governor?
I have attended many conferences as a speaker where the hotel expense was paid by the conference. My employer's expenses were the transportation.
I have also taken a couple of extra days as vacation days at my expense before or after conferences.
Alaska to NY is a heck of a trip, and is expensive. We don't know if there was a study stay-over, when were the tickets booked, coach, or first class?
I don't know what the airfare was when the trip was taken, I just searched travel.yahoo.com RT Juneau to Laguardia for 12/7 - 12/11 lowest nonrefundable ticket is $445, Business Class is $853 per person. (and that is with two week advance notice) The trip itself would take 11 to 17 hours.
study = Saturday
