everything was great except that me and my husband were choosen to sit in the very back of the plane when supposedly there wasn’t any available seats up front. When I went to go to the bathroom I saw plenty of seats available. Why would you put people in the 25th row knowing those seats don’t recline and also knowing seats were available elsewhere.
