In a statement issued late Tuesday afternoon, the airport authority disputed Air Transat's claims that no stairs were available.

"We had a gate available and air stairs ready in the event that the airline decided to deplane," the statement said.

The airport authority also said its staff was prepared to bring supplies beyond just bottled water to the stranded passengers, but never received clearance from the airline.
"We keep a supply of water, food, diapers and other personal hygiene necessities to support passenger needs in irregular operation scenarios, and were prepared to deploy these supplies," the authority said.

"Although our staff tried several times to contact the aircrew through the handlers to provide further assistance, the aircrew was non-communicative and did not take us up on our offers to assist further."

The airport authority also said its personnel urged the Air Transat flight crew to open the airplane's doors so fresh air could circulate, and offered to provide fans so that passengers could stay cool.

"Providing the best possible customer experience is a priority for the Ottawa International Airport Authority," the statement said.

"We are disappointed that Air Transat has not been forthcoming, transparent or accountable with information concerning their diverted flights."
