We complain to be a over 3 weeks ago and I've had no response whatsoever apart from an automated message. We complained about house flight from Portugal to London where we had to endure twodrunk 60-year old something men. They swore constantly and were extremely disruptive for the whole flight. Despite being obviously drunk the stewardess served them even more alcohol! They constantly removed their mask throughout the whole flight. We are written to be a asking then why these people were served more alcohol despite being drunk and why they were allowed to keep removing their masks. This will be the last time we fly with British Airways. If they cannot control passenger then I think this indicates a real safety issue
