Who are Airport Dimensions?


Since 2006 you have known us as Airport Lounge Development (ALD). Together with our airport and airline partners we have delivered an award-winning hospitality experience to millions of travelers across our network of airport lounges in the US, Europe and Middle East. This experience and our partnerships with over 25 airlines, have allowed us to build market leading insight on the changing needs of frequent travelers. To meet these rapidly growing needs, Airport Lounge Development has changed to Airport Dimensions. This change will allow us to deliver even greater value by exploring new dimensions in travel experiences designed around the traveler.
As Airport Dimensions, we understand how the spaces we create affect the quality of travelers’ time at the airport.

From a brief stopover to a leisurely wait, we aim to deliver great value in a travelers’ time with us. By designing, building and operating airport spaces for lounge and other experiences, we seek to not only enrich a traveler’s visit but also help airports become more competitive, retain airlines and generate more revenue. Airport Dimensions leadership team brings over 25+ years of relevant industry expertise, with its senior management team having worked in key leadership positions within airlines, airline lounges, hotel, restaurants and traveler marketing research. Under this leadership our network has experienced an 80% growth in locations since 2015.
