It's a tremendous pleasure to explore the Qatar Airways LHR Terminal facilities at London Heathrow Terminal 5. The lounge is great with lots of comfy chairs to unwind in, and checking in is a breeze. The courteous and helpful personnel makes for a great beginning to your journey. All things considered, it's a great place to start your journey, with quick access to everything you need in a tidy, contemporary setting.
