PROS: Less than half full; plenty of overhead space; friendly crew. CONS: I was 2-minutes late to check my bag (45-Minute Rule?) so had to wait 4-hours for next flight; wheelchair requested, but not at arrival; seats were very cramped - too narrow & too close to seat in front (I’m 5’9” tall & weigh 148 lbs).
