Who are 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 to our travelers. By designing, building and operating airport spaces for lounge and other physical and digital experiences, we seek to enrich a traveler’s visit while also help airports become more competitive, retain airlines and generate more revenue. 
Formerly known as Airport Lounge development (ALD) and established in 2006, we have built a network of airport lounges across the US, Europe and Middle East with ambitious plans to continue our growth globally. In July 2020 we expanded our physical offering for travelers with the acquisition of ONGROUND Hospitality and the Sleep Lounge brand sleep ’n fly, and enhanced our digital

experiences with the launch of e-commerce and relationship management platform Connecta. Together with over 50 airport and airline partners we have delivered an award-winning hospitality experience to millions of travelers. This has allowed us to build market leading insight on the changing needs of frequent travelers. And combined with our commitment to the philosophy of Spaces well built, Time well spent, our network has experienced 516% growth in locations since 2015. Under the leadership of a team with over 25 years’ experience in hospitality, airlines, airline lounges, and the food and beverage industry, we are looking to explore new dimensions in travel experiences designed around the next generation traveler.
