Sunwing Airlines system issue forces numerous flight delays at Trudeau Airport

Multiple Sunwing Airlines flights heading in and out of Montreal's Pierre Elliott Trudeau International Airport have been delayed due to technical issues.

The airline took to Twitter to explain that its provider is experiencing "a network-wide system issue, which has impacted check-in and boarding."

As of 12 p.m., five Sunwing arrivals have been delayed at Trudeau Airport and at least four departures have been stalled.

One Quebecer stuck in Mexico says she's stranded with no information as to how she'll eventually get home.

She says her flight was supposed to be Sunday at 4:10 p.m., but was rescheduled to 6 a.m., and then 2 p.m. Monday.
