Two Air Transat pilot have been arrested in Scotland on suspicion of being under the influence of alcohol before they were scheduled to fly a transatlantic flight to Toronto yesterday.

Members of the plane’s cabin crew flagged what they saw as a problem yesterday afternoon at Glasgow Airport shortly before the plan was to take off to Toronto.

The flight did not go and the airline says passengers were put up in hotels and will be flown to Toronto today.

As for the charges, Montreal-based Air Transat 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.”

Scotland Police say the 37 year old captain and 39 year old first officer were scheduled to appear in court today to face charges of being impaired through alcohol.
