We experienced technical issues with an application installed on some pilot iPads," said a spokesman.
"This issue was with the third-party application, not the iPad, and caused some departure delays last night and this morning.
"Our pilots have been able to address the issue by downloading the application again at the gate prior to take-off and, as a back-up, are able to rely on paper charts they can obtain at the airport.
"We apologise for the inconvenience to our customers."
American Airlines pilots use an app called FliteDeck, which is made by the Boeing subsidiary Jeppesen.
