Two Air Transat pilots have been arrested in Scotland on suspicion of being under the influence of alcohol before they were due to fly a transatlantic flight to Toronto yesterday, authorities say. The captain and first officer — aged 37 and 39, respectively —are scheduled to appear in court today to face charges of being “impaired through alcohol,” according to Police Scotland.

The plane’s cabin crew raised the alarm Monday afternoon at Glasgow Airport  shortly before Flight TS725 with about 250 passengers was to depart for Toronto.

Air Transat, a Montreal-based airline that operates both scheduled and charter flights, says it will not comment until an investigation is completed.

“Air Transat has learned of the arrest on July 18 of two crew members assigned to its Glasgow-Toronto flight,” airline spokesman Pierre Tessier said in a statement. “We will await the results of the investigation and judicial proceedings before commenting on the matter before making any further comments. The safety of our crews and passengers is, and will remain, a top priority at Air Transat.”

Passengers affected by the flight delay were put up in a hotel Monday night and booked on a new flight set to arrive in Toronto just after noon ET.

Among them are Colin McAllister and Justin Ryan, the interior design television stars better known as Colin and Justin.

The pair  shared their experiences about the delay on Twitter. They were thankful someone spoke out about the pilots, and said it’s “better to arrive late in this world than early in the next.”
