NEW YORK (CBSNewYork) – A technical glitch triggered delays for several airlines Monday.

The delays first popped up in Chicago, New York, Miami and Boston, then spread to Dallas, Atlanta, Detroit and Washington, D.C.

Southwest Airlines issued an international ground stop for about 40 minutes. It was lifted around 7:05 a.m.

American Airlines said the problem was related to AeroData, a company that makes aircraft location and balancing technology.

The glitch has since been fixed, but travelers are advised to check with their airlines before heading out to the airport.
