I am flying BA from Washington Dulles to Tel Aviv through Heathrow. IAD to LHR and back are on a 777 and then a 747-400, with PTVs and such. However, my flight from LHR to TLV and back is on a 767-300. I would assume this aircraft does not have PTVs. What kind of service on the LHR-TLV route should I expect? Meal service, Movies, etc.
