LINK. Mr. Isom said the new American wants to have a few things ready to go the day after the deal closes. That includes putting signage in airports to direct customers if they try to check in at the other carrier’s counters, to train workers on the other airlines’ policies, gates and lounges, and have a single crisis plan in place in case of an accident or incident. Soon after the merger closes, he said, the goal is to allow passengers to book flights on both carriers on a single itinerary and combine some operations in Fort Worth, which means bringing some employees from US Airways’ current headquarters in Tempe, Ariz. Within six months, the two hope to start moving their planes around, matching the size of the plane with the demand on a route. They also want to let passengers earn and redeem miles on the other carrier’s frequent-flier plan, and harmonize some product offerings such as food and beverages on board and align some passenger processing procedures, Mr. Isom said. By a year after the merger’s closing, the two plan to move to one computer system and a single website, combine their operations centers and align employee procedures and manuals. The latter is required to win a single operating certificate from the FAA. Only then can the two join their workforces, mix and match aircraft and crews and offer a single passenger experience.
