All my recent flying has been out of Gatwick due to destination. Enjoyed it, especially the F Lounge. On return we get through immigration with zero wait almost every time. I'm there again next month, and coming from the North, it's easier on the train to Gatwick than Heathrow so that's how I'm doing it. Shame the MAN-LGW service has gone. I'm HBO for a short trip to MCO. Will be back at LHR in Sept but likely to have dropped to silver by then so B lounge it will be.
