Delta will also use the lounge to host VIP guests on matchdays – issuing guests with airline-style tickets inviting them to check-in for the match at the lounge.
The airline-inspired Delta 360 Lounge includes an LED-lit runway, full service bar, dining area, and TV screens all within a 108sqm space.
The new facility will be open daily and is expected to attract 250,000 visitors per year. The lounge will be used for continental breakfasts for guests of both hotels, as well as an executive lounge space during the day.
Simon Hunter, head of venue and brand at Chelsea FC, said: "We’re excited to be opening another new facility at Stamford Bridge. Particularly one with many uses for business and leisure guests like the Delta 360 Lounge, which provides an additional option for breakfast, acts as an executive lounge for the hotels and can also be used as part of hospitality on matchdays. We pride ourselves on being London’s most complete venue and developments like this enable us to continue to hold this reputation."
Delta has opened lounge-themed spaces in the grounds of the US sports teams it sponsors. These include baseball’s New York Yankees, hockey's Los Angeles Kings and American football's Minnesota Vikings.
