Hello, My experience with the Air China Sales Office in London was quite smooth and pleasant. The staff were polite and patiently helped me with my ticket change request. I appreciated how they explained everything clearly, especially about flight timings and baggage rules. The office was easy to find and had a calm, professional vibe. I left feeling satisfied with their customer service and would definitely visit again if needed. for more information visit: https://rightcheckin.com/airlines/air-china-city-sales-office-in-london/
