Wondering if there is a difference in terms of quantity and quality when flights serve both lunch & dinner on a transpacific route. Flew CX839 YVR-HKG a year ago and the meal service was exactly like that. Lunch after takeoff and dinner served 90 min B4 landing in HKG. However, the meals were almost the same: Rice & Fish (Lunch) & Rice & Chicken (Dinner). So is the term Lunch and Dinner used to indicate when the meal is served according to the flight schedule or if there is a major difference in terms of what you get? Both meals were great but I didn't see anything more special in the Dinner selection than the lunch. The night flight has supper/breakfast service in which there is a major difference between them. However, can't see much difference between lunch/dinner.
