Travellers heading out of the Calgary International Airport were asked to arrive early on Monday after an outage at a couple of screening points caused delays.

Officials say CATSAs screening equipment at the D and E checkpoints was affected and other plans were made to screen those passengers.

US-bound guests at screening point E were delayed for about 75 minutes and were screened using alternative procedures.

International guests travelling through Gate D were rerouted to C, which caused delays for passengers at both gates.

Officials are still working to resolve the issue but say wait times were back to normal just before noon.

Eight US-bound flights were delayed as a result.
