Interesting they will do the switch over a long period of 90 days rather than overnight as DL/NW did. The small remainder of US flights will still merge overnight, but will only be four per cent of all AAL reservations. It helps some of the older US employees still remember their version of Sabre. So far, I'd say the merger had been operationally smooth and employee morale is pretty high, the botched new F class meals aside. If this goes well, Parker will be eating Smisek's lunch everyday for years to come.
