With huge windows and plenty of open space, the mezzanine in Terminal 1 provides the best airfield views at Minneapolis-St. Paul International (MSP). And until recently, 5,000 square feet of the prime airport real estate was used for storage. That’s right, storage. Late last year, however, MSP began leveraging its second-story asset to create a new “luxury amenity.” It now leases the mezzanine space to MAG USA for an upscale common-use passenger lounge. MAG USA is the U.S. subsidiary of U.K.-based Manchester Airport Group, which owns and operates four British airports, including Manchester Airport and London Stansted Airport.
