Sorry, not as hot as the Air Canada price glitch but nonetheless, still HOT!
Fly WOW Airlines, stopping over in Reykjavik (the hub) for $347CDN taxes in with NO luggage (a small carry such as a purse or laptop bag are free) and $527 with luggage. You need to book one-way out of Toronto (in CDN$) and then back from Tel-Aviv is USD$ to get the low price.
Best way to search down a flight is the Matrix--UPDATE--not working well--use GoogleFlights--click here to get to it. I'm finding dates out of Toronto on some Sundays, Tuesdays, and Fridays for $200 (for those who would travel on a Friday).
Coming back, flights are $119.99USD! You must change the currency to USD though as I find it defaults onto Canadian dollars (must know I'm in Canada).
You can use this link for a date in January that I've set to USD if you wish or just change it from CAD to USD in the website address when Google or the Matrix takes you to the WOW page. Sundays, Tuesdays, and Thursdays out of Tel-Aviv for that price.
Book before they're gone!! Don't hesitate or you'll be sorry!
