Chris789, I don't fly from LGW very often. My outbound journeys (minus the issue I described below) have been positive and South is much improved. Where I would grumble is about the inbound experience as all three journeys have encountered lengthy delays for both immigration and collecting baggage. One flight parked on a remote stand from which we were bussed to North not South Perhaps I have been unlucky, but my issues don't appear to be unique.
I would say they are looking after their outbound pax as it is they who browse the shops. Inbound pax are perhaps a necessary evil and investment maybe hasn't been so forthcoming
