A company plans to double its number of lounges available at UK airports to 16 by the end of 2018.
No1 Lounges then plans to expand to 24 sites by the end of 2020 in an industry it estimates to be worth £3.4 billion globally.
The additional lounges will be at airports where No1 already has a presence and some new locations.
No1 is owned by former Tony and Olivier award-winning West End theatre producer and entrepreneur Phil Cameron, who is also CEO.
Founded in 2006, the firm recorded a turnover of £23 million last year, a figure which is set to increase as the brand expands its UK airport coverage.
It has eight lounges at Heathrow, Gatwick, Edinburgh and Birmingham airports.
Three different types of lounge – My Lounge, No1 Lounges, and Clubrooms – are available,. with entry starting at £18 per person.
Cameron said: “Premium travel is changing rapidly – it is no longer just about turning left when you board the plane.
“Passengers are increasingly looking for affordable luxuries and more personalised experiences, especially as many airlines are streamlining their offerings in order to compete.
“We believe it is about giving consumers greater choices and a stylish send-off – all without breaking the bank”
