American Airlines is working on a problem that is delaying dozens of flights across the country.
Airline spokesperson Casey Norton said an app on iPads used by pilots stopped working properly.
The iPads have several uses, including mapping and flight planning.
Norton said the airline has discovered a solution and is working to get all flights back on time.
He could not say if the problem affected Tulsa International Airport, but according to TIA's website all American flights are on time.
