While El Al has announced Dreamliner service from JFK, Newark, Los Angeles, and Miami, they have left Boston and Toronto on the schedule with their ancient 767s that have angled business class seats and overhead entertainment.
El Al has now announced that Boston will get 777 service from October 28-March 28. Interestingly, while the 777 does have first class, El Al is not currently selling first class seats on the route.
In Toronto, where El Al competes against an Air Canada Dreamliner, El Al will continue to use a 767. Air Canada commands a significant price premium in that market.
In other Tel Aviv route news, Norwegian will start flying nonstop from Oslo to Tel Aviv starting in October. You can fly on SAS from Newark to Oslo and on Norwegian from JFK to Oslo.
In December, OneWorld carrier LATAM will also begin 3 times weekly Dreamliner service from Sao Paulo to Tel Aviv. El Al failed to operate this route profitably in the past, but LATAM can take advantage of their connections to other cities that will help with traffic on the route.
