I recently took a flight with United Airlines LHR Terminal from Terminal 2 at London Heathrow, and the experience was better than I had anticipated: check-in was easy, with friendly staff and short wait times; the terminal itself is modern, roomy, and easy to navigate; security was quick and efficient, and I enjoyed the peaceful atmosphere throughout; I had access to the United Club Lounge in Terminal 2B, which provided a comfortable space with free food, comfortable seating, and a great view of the airfield; boarding was punctual and well-organized, with clear announcements and polite staff; the entire United experience was polished and professional; I wouldn't think twice about flying through LHR Terminal 2 with United again.
