Travellers booked on SkyGreece flights experienced another morning of frustration at Pearson International Airport on Thursday.

A 7 a.m. flight was delayed, making it four-straight days of flights that haven’t taken off.

The next flight is scheduled to leave Toronto for Greece at 2:30 p.m.

“There were a couple excuses. One was the pilots were sick, and the other one was they needed a part for the plane and it’s in Montreal,” Mijo Cupor, a traveller from Sudbury, told CityNews on Thursday.

“Well, you have so many flights from Montreal to Toronto, the part could have been here a couple days ago.”

SkyGreece has posted a message on its website that says the airline will have to delay all flights until today because of “operational considerations.”
