Two Air Transat pilots have appeared in court after being arrested at Glasgow airport on suspicion of being impaired through alcohol.

Captain Jean-Francois Perreault, 39, and Imran Zafar Syed, 37, were remanded in custody.

They were arrested at the airport on Monday on suspicion of being under the influence of alcohol. They were charged with breaching Section 93 of the Railway and Transport Safety Act at Paisley sheriff court.

The men appeared in court separately represented by union-appointed solicitors, The Times reported.

They made no plea and are expected to appear before the court again in eight days. Sheriff Susan Sinclair remanded them in custody for prosecutors to investigate further.

The Canadian pair were due to fly the Air Transat Airbus to Toronto with 250 passengers on board. The flight was held up overnight and eventually left at 10.30am on Tuesday.

Air Transat apologised to those passengers affected and offered passengers compensation of C$200 off their next flight as a “goodwill gesture”.

In a letter it said: “Please accept our sincere apologies for the disruption caused by the delay of your flight. While it is our policy to do everything within our power to ensure on-time performance, regrettably, this is not always the possible.”

The airline said the safety of its crews and passengers was its top priority and that it would await the results of court proceedings before commenting further.
