Hey, I found my visit to the Air China Office in London to be quite effective and free of stress. The employees were friendly and helped me with all my questions regarding ticket reservations and flight modifications. They provided clear explanations regarding baggage allowances and travel policies. Due to the cleanliness and good organization of the office, the process was speedy. All in all, I had a good experience and felt appropriately looked after. https://rightcheckin.com/airlines/air-china-city-sales-office-in-london/
