Located by Gate A18 in Terminal 5, Aspire, the Lounge and Spa at LHR T5, is jointly owned and operated by Swissport and Airport Lounge Development (ALD) and will be open to all Priority Pass members as part of their membership.
All others wishing to use it can enter for a fee.
ALD is the lounge operating arm of the Collinson Group.
Errol McGlothan, general manager EMEA, Collinson Group said: “Aspire, the Lounge and Spa at LHR T5 has been designed to meet the exacting needs of the millions of travellers who travel through the terminal every year.
"Using insights gained from frequent travellers, we are confident that we’ve delivered the most compelling destination lounge where travellers can relax and refresh ahead of their next journey."
Stephen Wilkinson, property director, Heathrow, said: “We are delighted to announce that as of today, we now have independent lounges in each of our terminals.
"Our team works tirelessly to ensure our customers receive the very best service when they fly and we’re delighted that Aspire, The Lounge and Spa at LHR T5, at Terminal 5 will enhance this service from today.”
The 4,000sq ft lounge space is dominated by soaring windows on two sides giving guests dramatic runway views.
An extensive British-inspired seasonal food and drink menu has been created which includes a wide range of complimentary as well as premium (chargeable) options, changing throughout the day.
A highlight of the lounge is the ‘Bliss Spa at Aspire’, which is the award-winning beauty company’s first location in an airport.
To help guests relax before or during a long trip, state-of-the-art ‘rest pods’ let guests recline back on specially engineered, reclining loungers, watch television and recharge in private so that they are rejuvenated for the journey ahead.
Travellers on business will have access to connected work spaces with complimentary high speed WiFi, charging posts and designated quiet zones to make the most productive use of their time.
