The day started at 230 today. Made it to st Louis and departed plane at gate 12. Went to gate 34 and waited. Susan asked what time boarding the flight was and it was in about 5 minutes. At that time we noticed that the gate had been changed to gate 12. Shit we had to go back across the airport. All went fine and we got on the plane. I choose our seats and the guy on the isle seat was kind of a chair hog with the arm rest. Rather annoying.
