Dozens of JetBlue Airways flights were delayed Friday morning after a computer failure limited the airline�s ability to dispatch planes.

The system was restored by 10:30 a.m. but the airline warned that delays would persist throughout the day. As of 11 a.m., there were 40 delayed flights, according to JetBlue.

At New York�s John F. Kennedy International Airport – JetBlue�s largest base of operations – about a third of all the airline�s flights were listed as �delayed� on the flight monitors. The typical delay was about 90 minutes.

The airline blamed �IT network connectivity issues� but did not elaborate.

Computers are used to calculate weight, fuel and other key information needed before a plane can leave the gate.
