LHR-TLV-LHR. Flew out on B747 which had individual seat back screens with a choice of films playing in a fixed pattern. Return flight on B767 with overhead screens with no choice of inflight entertainment screens old and poorly spaced made viewing entertainment a bit of a challenge. Both aircraft's were clean with inflight magazine and the usual seatback options. No amenity kits just headphones pillow and blanket. Boarding at LHR slow and delayed due to late arrival of incoming aircraft. Security checks very through staff ok. Meal Service was slow as there seemed to be a huge number of "Special" meals that had to be distributed before the main service started. Quite a bit of hand luggage slowed down getting on and off the plane - also no formal boarding process just a first come first served. Outbound flight late inbound flight more or less on time.
