Delta Air Lines says "limited departures" are resuming after a power outage knocked out its computers systems and operations in Montreal and around the world.

But the airline told its customers to expect delays and cancellations to continue as it works through its problems.

Several flights were delayed at Montreal's Pierre Elliott Trudeau International Airport this morning.

Delta said the computer crash was caused by a power outage in Atlanta, where the company is headquartered, early Monday morning. 

Delta said customers whose flight had been cancelled or "significantly delayed" are entitled to a refund.

Delta is one of the world's biggest airlines, with more than 5,000 flights daily to six continents.
