American Airlines' computer system was restored around 4:30 p.m. Tuesday after being down for several hours, bringing flights to a halt system-wide. American expected that flight delays and cancellations would continue throughout the day.
About 700 American and American Eagle flights were canceled and 800 were delayed, according to Flightstats.com. Six outbound and four inbound American flights were canceled at Logan International Airport, according to the Massachusetts Port Authority website, with several more experiencing delays of 45 minutes or more.
The airline made arrangements for passengers who were already at the airport to rebook on other airlines through an American agent, or at another airline's ticket counter using their ticket number. Those who had to travel on Tuesday but were not yet at the airport could rebook through American or another carrier, and American would honor the fare difference. Customers who decided not to travel Tuesday could change their reservation for free or get a full refund.
