I have tried the new London Lounge LHR and it's really great
My question is with my new gold/sapphire card and the love of being airside is there a limit to the time I can have there say my flight is earlier evening for example can I be there in the morning, such is my enthusiasm for maxing the time spent. This is for a new flight that day not a connecting flight.
If there is a problem with earllier as possible check in is there an airside pass purchasable.
