Following my emails to BA (as mentioned in earlier posts) I received a very pleasant telephone call from their customer care department this morning.
We had a long chat about my experiences including the First Lounge in T5. It seems that BA are indeed listening to customer feedback.
Interestingly, this call came as a result of my email to customer services.
I sent emails to the addresses suggested my first_class_please. None of these has been even acknowledged by their recipients. Such bad manners is disappointing from senior personnel in a customer focussed company.
