Thanks and Austrian?
EWR-YYZ is a short hop at the beginning of the trip, after that you're in a proper business class seat all the way to TLV.
And while YYZ is horrific, would you rather have the connection at that point of the journey and continue in a lie flat business class seat, or would you prefer to have to go through a connection after 6-8 hours of flight, only to be put in fake J (economy seat with middle seat blocked off) for the final leg?
