Just Goggled Aspire lounge Luton Airport. The new larger lounge which opens in the spring will now have full size Spa facilities and snooze pods. Whether that lounge can accommodate a full load going to New York on top of its normal passengers remains to be seen.
I can only assume they have taken over the empty space on the other side of the staircase as I am sure there was provision for 2 lounges when the terminal was built.
