Lots of threads discuss the order for choosing meals (e.g., "AA292/293 F Seating and FEBO"), and some, such as the FAQ, do helpfully note that meals are generally served front-to-back regardless of the order for choosing. However, I haven't seen a discussion of the serving order on two-aisle planes, especially 777 in F. My recollection from my last few flights, is that U.S. to LHR (even flight), meals were served left (port) aisle front to back, then right aisle front to back; LHR to LAX (odd) they were served right (starboard) aisle front to back, then left aisle front to back.

Is this a consistent thing? It can make a difference depending on how one wishes to allocate flight time.
