I agree Tim, it has improved substantially under the current ownership, although there is still work to be done. Right now the South Terminal seems to be getting the attention.
I suspect part of the challenge is that BA are not the major player at the airport so don’t call the shots when it comes to prime space for lounges etc.
Still far better than Heathrow in my books. If the staff at LGW are miserable I’m not sure how you would describe the HAL bunch.
