Used to be my favourite London airport but is now absolutely woeful. The "reconfigured" area for awaiting flights after security checks is an absolute mess - blockages and no adequate flow through to gates. Seating blocks access to gates. Often waiting on the plane to disembark for over an hour and baggage handling takes even note time after that. Departures is as bad with gates reassigned last minute with disruption to plane loads of people, including families with babies. The car rental village shuttle bus is slow and definitely not on 10 minute loop. Dismal.
