Here is another link that won't ask you to sign in or register if you are on a mobile device. The summary is that saturday is the day that US Airways and American merge their computer systems. They don't expect delays but we all know how that goes.
Flying American Airlines on Saturday? You might want to check in early.
The US Airways brand will fly into the sunset Saturday as American Airlines embarks on the perilous task of integrating passenger reservation systems.
Fliers of the world's largest airline won't have to do anything differently, although checking in early and leaving extra time is probably wise.
US Airways will cease to exist Saturday as far as customers are concerned. The combined airline moves to one website, one mobile app, and a single set of travel policies and frequent-flier benefits. Fort Worth, Texas-based American and US Airways merged in late 2013.
Behind the scenes Saturday, American will be combining reservation systems, often called the computer backbone or brain of an airline.
In other airline mergers, combining systems has caused problems. Notably in 2012, Chicago-based United Airlines combined reservation systems, moving to Continental's. It resulted in months of rampant delays and cancellations that led to customer defections and damaged profits.
American Airlines officials say they have spared no expense to decrease the chances the airline will have trouble Saturday but can't guarantee complete success. Here's what American has done so far:
• It switched to the larger airline's reservation system, which requires moving less data and less retraining of employees.
• In July, it began draining US Airways reservations from the system, leaving fewer records to migrate, just 4 percent of all reservations.
• American did six full-scale tests of the migration with 5 million mock plane reservations.
• Staffing levels at airports will be increased 20 percent Saturday.
• American's flight schedule Saturday has been reduced by some 200 flights.
• Airport agents and reservation agents had extra training.
• USAirways.com will automatically redirect to AA.com on Saturday, and the US Airways mobile app will be disabled.
In airports, including O'Hare International, American has already combined ticket counters and gates with US Airways. American uses O'Hare as a hub and is the second-largest airline there, next to United.
Several years of other behind-the-scenes integration work is left to complete, involving flight attendants, pilots and maintenance teams. It will take a couple of years to repaint US Airways aircraft.
