UPDATE: March Madness at Trudeau Airport delays flights to US

Flights to the United States have resumed at Montreal's Trudeau International Airport after an early morning computer malfunction caused a 4.5 hour delay for thousands of travellers.

The glitch knocked out the baggage system to all US flights at 4:45 Saturday morning and created a huge backlog of disgruntled passengers. It took more than two hours before the airport publicly acknowledged the problem. 

The airport authority also declined CJAD800's request for a recorded interview, but said they were working to fix the problem as quickly as possible. Aéroport de Montréal confirmed that normal baggage operations resumed just after 9AM, via Twitter, but the damage was already done. 

US baggage system, operations progressively back. We invite you to double-check with the airline cie status of your flight before heading to the airport. Thank you for your understanding.

Montrealer and best-selling author, Catherine McKenzie, was among those temporarily stranded. She arrived at the airport just as the problem began and said it didn't take long before the Departures area was "just nuts." 

"So, all the flights (were) delayed and there's about a thousand, maybe 15-hundred people in line, waiting to put their bags on their aiplane," said McKenzie. 

Some passengers also took to Twitter to vent their frustrations and ask why there are not back-up plans for situations like this.

The glitch caused a huge delay for U-S customs agents. They were forced to match baggage with individual passenegers on a 1-on-1 basis before allowing anyone to board their aircraft.
