(RNN) - American Airlines have restored their reservation system, the outage of which grounded all flights across the U.S. However, delays are expected in getting travelers to their destination.
The company could not access its reservation system for most of Tuesday.
More than 700 flights have already been canceled.
A statement on American Airlines Facebook page read:
UPDATE as of 3:30pm CDT: Our systems have been fully restored, however we expect continued flight delays and cancellations throughout the remainder of the day. We have made several options available to our customers:
If customers must travel today and are already at the airport, they can rebook on another airline by visiting an American Airlines agent or by going to the other airline's ticket counter with their electronic ticket number.
If customers must travel today and are not yet at the airport, they can rebook through American Airlines reservations or through another carrier and American will honor the fare difference.
If a customer chooses not to travel today, there will be no charge for reservation changes or a full refund will be provided.
It is important to note we see no evidence that today's technical outage is related to the tragic events in Boston.
We will continue to provide more information throughout the day as we make progress in resolving this issue. We apologize to our customers and our people for this inconvenience.
The company posted earlier on Tuesday on both Facebook and Twitter the system-wide delay would last until 5 p.m. ET, and apologized to its customers for the inconvenience. The glitch was fixed 20 minutes ahead of that deadline.
The company was not able access the reservation system, but there was not a problem with the system itself, which is run by Sabre.
