The FAA in the United States has extended its flight ban to Tel Aviv's Ben Gurion airport for up to another 24 hours and will continue to monitor and evaluate the situation.
For a second straight day, Air Canada has cancelled its evening flight from Toronto to Israel. It has also cancelled its return flight from Tel Aviv.
The cancellations are wreaking havoc across the international travel industry, with agents like Laval-based Dan Abitbol dealing with panicky calls from clients wondering how they are going to get home.
Abitbol is a Laval-based travel agent who books visits to Israel for a largely Jewish clientele.
He says many of his clients have been left stranded by the ban on flights to Ben Gurion airport, and they are wondering how they are going to get home.
"The hotels are overbooked, people have to stay in the condos they've rented for extra days, and of course people have had to cancel trips," he says. "It's been a real mess."
He adds that Israel doesn't have any allies in the region, making it even more difficult for passengers to make alternate arrangements.
"Here, someone can drive to Plattsburgh or Burlington and catch another flight and find another way home," he says. "Here, Ben Gurion airport is the only way to leave the Middle East and get back home."
Other travel agents are reporting a spike in cancellations of trips to the Middle East.
