Let me tell you about my experience flying with United Airlines LHR Terminal at London Heathrow Airport Terminal 2. It's quite simple to check in when you get there. Long queues are not a concern because you can complete it online via the mobile app or at a self-service kiosk. After checking in and passing security there are several of options for where to eat or shop for last-minute necessities. You can recharge your devices before the trip thanks to the charging stations and the incredibly comfy seating places. The employees of United Airlines are also always there and willing to help if you ever need it. Every step of the process is easy and hassle-free!
