US carrier Delta is to buck the airline trend of shrinking premium cabins by increasing first class capacity on its domestic flights, perhaps hinting that a recovery in luxury travel may be on the cards.

The airline announced last week that from this fall it is to offer first class on all internal US flights longer than two and a half hours, an increase of some 50 routes from the current first class availability.

If you’re traveling from London’s Heathrow Airport aboard Delta Air Lines or one of its SkyTeam partners, you’ll soon be able to take advantage of this futuristic and luxurious new lounge.

The lounge is open to international first and business class passengers as well as SkyTeam Elite Plus passengers.

The two-level minimalist styled lounge features a spa, restaurant, wine bar, oxygen bar and entertainment hub.
