There was something that bothered me a little. Waiting to leave from Jax airport toDCA. I was told there were a lot of empty seats which there were I prefer an aisle seat it was selected by the window for me, so I asked if I could change she abruptly said no and said the government would not let you but they are empty I said. She said well when the door closes the crew does what they want. So rather confusing and she seemed annoyed.
