Flown with various airlines but this was definitely the worst. Could not do online check in 24 hours in advance. Went to airport 3 hours ahead to try getting my wife and I seats together but to no avail. I am assuming if I offered to pay, they would probably be able to find us seats together. It is simple ridiculous why AA charges for getting assigned seats. Don't we pay enough for the flight to begin with? There were lots of families separated on the flight due to the airline's greed. Airline said flight was full but soon after called standby passengers and assigned them seats together. Staff at the boarding gates were rude and uncooperative. Leg room and space between passengers on the aircraft is horrible. I am only 67 inches tall and could hardly move an inch in my seat.
