A Canadian who has been stranded in Cancun for over 24 hours after her Sunwing Airlines flight to Toronto on Sunday was delayed due to technical issues, says the lack of communication has been frustrating.

Shabana Sultani told CTV鈥檚 Your Morning that passengers are running out of medications and supplies at Cancun International Airport, and weren鈥檛 provided with money for extra food and water until they were shuttled to a hotel in the middle of the night.

鈥淭he thing that's bothering everybody the most is the lack of communication,鈥� she said. 鈥淲e're not being given a direct report or even an estimate for an actual time for when we're going to be able to leave.鈥�

According to Sultani, the flight to Toronto was delayed by 10-minute increments for almost three hours, and the flight has already been cancelled five times since Sunday.

She says she has no idea when she鈥檒l reach home and has been trying to make concessions about her return date to her workplace.

, the flight delays were the result of a network-wide system issue that has impacted check-in and boarding. The technical issue is impacting several carriers globally, the airline said.

鈥淲e are working diligently with our technology provider to resolve the issue as soon as possible so that regular flight operations can resume,鈥� a spokesperson for Sunwing said in a statement Monday.

鈥淲e strongly encourage all customers with departing flights over the next day to check their flight status before heading to the airport.鈥�

Sunwing's website lists all flights scheduled for Monday 鈥� more than 40 鈥� as being delayed, some by more than 12 hours. 

Several of these were connecting Canadian cities to popular tourist destinations in the Caribbean like Cuba and Aruba.

鈥淚 haven't travelled in over two years and 鈥� we decided to book in good faith to take this time to relax,鈥� Sultani said.

鈥淏ut, this is the worst thing I鈥檝e ever experienced. I鈥檓 going to need a vacation to get over this vacation.鈥�

, an independent non-profit organization of volunteers, say on its website that passengers are owed compensation for delayed and cancelled flights that are within the carrier鈥檚 control.

According to them, travellers are entitled not just to food, lodging, and prompt transportation to their destination, but also to up to for the hardship.

Sunwing has not provided a timeline for when the issue will be repaired.

Customers with a departing flight over the next 12 to 24 hours should check their flight status, the airline says.
