It will take more than volunteers to solve the problems
The ba website proudly displays arrival and departure times that suggest things might be getting back to normal. I arrived on BA 1403 on Sunday evening, according to the website we 'arrived' at 2024, only 59 minutes late. In reality with no stand for 30 minutes and a further hour and a half for a set of steps to all us to escape, we actually arrived at the terminal 2 hours later than stated. By then all connections had been lost, the hold doors were only just being opened at 2225, no doubt to avoid increasing the baggage mountain and universally everyone on board said they would never fly BA again.
Of course some of us will, I regret having 8 more bookings from T5, but there appears to have been no crisis planning at all, inadequate equipment available, after all a set of steps for an A319 cannot be that difficult to find surely, and no visible management at all. The crew remained cheerful but apologetic ('there is nothing you can say that we haven't already heard'), the passengers discussed opening the doors and pulling the red handle as shown on the safety video but for many, making non-BA connections, the reality was probably having to buy a new ticket at considerable cost. They certainly will not fly BA again.
