Lounge membership programme Priority Pass has passed the 900-lounge milestone, with over 170 lounges having been added in the last 12 months.
The group said that the Asia-Pacific region was a major contributor to growth, with 24 lounges having been added this year alone, and over 80 since January 2015. Of these over 60 are located in China.
The Europe, Middle East and Africa region has seen 22 lounges added, while in Russia over 30 facilities have joined the programme since April 2015.
The Middle East has seen seven new members, with ten new lounges joining in the US.
In October last year Priority Pass announced a refresh of many of its services to "reflect the changing needs of frequent flyers".
Updated benefits included digital membership, a new website and smartphone apps, as well as new golf and car rental offers for members (see news October 2015).
