I don't know if Sara flew a Chartered flight. I highly doubt it. The first thing she did (literally) when she got into office is put up Frank Murkowski's private jet that he bought with state money even after the voters said NO! He was an arrogant SOB. She sold it on Ebay (or tried, LOL!!). She said then that she would use regular airfare like the rest of the world.
However, that said, I doubt Alaska Airlines would dare to tell this Governor no. No is not an option with Sara
Like I said, a very special lady. I suspect she had a nurse or doctor fly with her home as a precaution.
