The year in lounges: Delta One Lounge coming to SEA and more for 2025   

SEA Delta One Lounge

This year, the Delta One Lounge journey continues, along with much anticipated refreshes to Clubs in Delta’s hometown ATL airport, a Club expansion, and three new locations at hubs. 

Here’s a look at what customers can look forward to this year.  

ATL 

As part of the Concourse D renovation, a new 23,000 square-foot Club will open near Gate D16 this spring. This will be the first new Club at Delta’s ATL homebase since 2016 and the second-largest Delta Sky Club at the airport. Spring 2025

SEA   

The Delta One Lounge experience comes to the northwest coast with the opening of Seattle-Tacoma International’s Delta One Lounge this summer. The nearly 11,000-square-foot space will feature an open-air terrace with stunning views of Mt. Rainier. At nearly 14,000 square feet, the A11 Delta Sky Club will give SEA customers more options to relax and dine pre-flight.  May 2025 

SLC 

A second Club will open at Salt Lake City International Airport on Concourse B (joining the Concourse A Club, opened in 2020). The expansive, near-34,000-square-feet Club will be one of the largest in the network. Q4 2025

PHL

The Delta Sky Club near the Terminal D/E connector will get a 2,000-plus-square-foot expansion. Q4 2025

With 56 lounges and a footprint of 700,000 square feet, the Delta Sky Club network is the largest of any U.S. domestic airline.
