While Delta is by many metrics considered the most premium airline in the United States, one area where the airline has historically lagged the competition is when it comes to premium lounges dedicated to international passengers. For nearly a decade, American has had Flagship Lounges and United has had Polaris Lounges, while Delta didn’t introduce dedicated premium international lounges until 2024.
Fortunately the dynamics have quickly changed, with the introduction of Delta One Lounges. Delta has now opened four of these premium lounges, with several more in the pipeline (though we’ll have to be patient). In this post, I want to go over all the details of the lounge network, including the locations, access requirements, and more.

Delta One Lounge details, hours, & locations
Delta currently has four premium lounges, in New York (JFK), Los Angeles (LAX), Boston (BOS), and Seattle (SEA). These are called Delta One Lounges, with Delta One being how Delta markets its premium business class product. Let’s go over the locations, as I find these to be among the best lounges in the United States.
Delta One Lounge New York (JFK)
The Delta One Lounge New York (JFK) was the first lounge to open. It’s located in Terminal 4 of New York Kennedy Airport, between Concourse A and Concourse B, right near the security checkpoint. The lounge is open daily from 4:30AM until 11PM.
This is Delta’s biggest airport lounge to date, as it’s around 40,000 square feet, with seating for 515 guests. The lounge features some pretty awesome amenities, ranging from a full-service brasserie, to a casual chef-assisted market with open kitchen, to a bar. There’s also a dedicated wellness area, as well as a year-round terrace.
See this post for more details on the Delta One Lounge JFK, and read my review of the Delta One Lounge JFK.
Delta One Lounge Los Angeles (LAX)
The Delta One Lounge Los Angeles (LAX) was the second lounge to open. It’s located in Terminal 3 of Los Angeles International Airport, immediately adjacent to the Sky Club, and is accessible directly from the Delta One check-in area. The lounge is open daily from 4:15AM until 10:00PM.
This lounge is much smaller than the JFK location, as it’s around 10,000 square feet, with seating for 191 guests. The lounge features a la carte dining throughout, a sushi counter, and signature bento boxes, rotating every two weeks, highlighting a Delta One destination from LAX. The lounge also has a dedicated wellness area with massage chairs and zero-gravity chairs, as well as a year-round terrace.
See this post for more details on the Delta One Lounge LAX, and read my review of the Delta One Lounge LAX.
Delta One Lounge Boston (BOS)
The Delta One Lounge Boston (BOS) was the third lounge to open. It’s located in Terminal E of Boston Logan Airport, by gate E13, inside the Sky Club. The lounge is open daily from 3:30PM until 7:45PM
This is the smallest lounge in the network, as it’s around 6,700 square feet, with seating for 121 guests. The lounge is almost like a huge restaurant, as it has a heavy focus on a la carte dining, with the menu leaning heavily into seafood from New England. The lounge has dedicated restrooms, though the shower suites are shared with the Sky Club.
See this post for more details on the Delta One Lounge BOS.
Delta One Lounge Seattle (SEA)
The Delta One Lounge Seattle (SEA) was the fourth lounge to open. It’s located in Concourse A of Seattle Tacoma Airport, by gate A11, and it’s stacked on top of the Sky Club. The lounge is open daily from 8:30AM until 4PM (and until 6PM on Mondays, Tuesdays, Thursdays, and Saturdays).
This lounge is similar in size to the Los Angeles location, as it’s around 10,000 square feet, with seating for 221 guests. The lounge features a la carte dining, a huge wraparound terrace, and views of Mt. Rainier. The lounge has dedicated restrooms, though the shower suites are shared with the Sky Club.
See this post for more details on the Delta One Lounge SEA.
Future Delta One Lounge locations
While Delta did a great job opening four Delta One Lounges pretty quickly, we’re going to need some patience before the next lounges open. We know that Delta is planning more of these lounges for other hubs, but the timeline remains to be seen.
A Delta One Lounge Atlanta (ATL) is expected to open in 2028. We also know that Delta One Lounges are planned for Detroit (DTW), Minneapolis (MSP), and Salt Lake City (SLC), but with no timeline.
Delta One Lounge access policies & rules
Who can access Delta One Lounges? The access restrictions are the same across the lounge network (with one specific carve out for Boston), and there are generally three pathways to accessing these lounges. Note that they don’t follow standard SkyTeam lounge access rules. Let’s break it down by entry method.
Delta One passengers get access
As you’d guess based on the name, the primary people who have access to the Delta One Lounge are Delta One passengers. This is the name of Delta’s premium business class experience. So if you have a same day Delta One ticket (whether arriving or departing), you get access to the Delta One Lounge.
It doesn’t matter if you paid cash for your ticket, redeemed miles, or upgraded, as access rules are the same regardless. Note that no guests are allowed to be brought in.
I should mention that you need to physically have access to the sterile area of the terminal in order to access a Delta One Lounge. In other words, if you’re just arriving internationally without a connection, you wouldn’t be able to use the lounge if you couldn’t get past security after clearing immigration and customs (which requires an outbound boarding pass).
Select partner airline premium passengers get access
It’s not just business class passengers on Delta who get access to the Delta One Lounge. First and business class passengers departing or connecting on Air France, LATAM, KLM, Korean Air, and Virgin Atlantic, also get access to Delta One Lounge.
Keep in mind that in some cases it might not be practical to use a Delta One Lounge when flying these airlines, due to terminal setups. However, access is allowed. Note that no guests are allowed to be brought in.
There is one exception to this rule — Air France and KLM business class passengers can’t use the Delta One Lounge Boston due to capacity constraints.
Delta 360 passengers in first class get access
Delta 360 is Delta’s invitation-only elite status. These passengers can use the Delta One Lounge whenever traveling same day on a first class ticket. Delta 360 passengers are the only ones who can pay to bring guests into the lounge.
Delta 360 members eligible for access may bring their immediate family (spouse or domestic partner and children under the age of 21), or up to two companions, for an entry fee of $100 or 10,000 Delta SkyMiles per person.
Bottom line
Delta has four of its Delta One Lounges, located in New York (JFK), Los Angeles (LAX), Boston (BOS), and Seattle (SEA). The lounge network is expected to expand to other hubs in the coming years, though it sounds like it’ll be at least a couple of years before the next lounge opens.
These lounges are open to Delta One passengers, select SkyTeam business class passengers, and Delta 360 members traveling in first class.
I have to say, Delta has done an absolutely stellar job with these lounges, and I’ve very much enjoyed my visits to these facilities. They have great food, super friendly service, and nice decor and amenities.
What do you make of the Delta One Lounge network?
My husband and I were denied entry to the Delta One Lounge during our four hour connection in Seattle yesterday.
Our entire ticket was purchased with Delta on both Delta and Korean Air metal.
Our route:
Korean Air, Prestige Class, DL7837: Seoul to Seattle
Delta, First Class, DL2613: Seattle to San Diego
Based on Delta’s official admittance rules, we believe I should have been admitted as we were “connecting” from an eligible partner...

Based on Delta’s official admittance rules, we believe I should have been admitted as we were “connecting” from an eligible partner (Korean Air):

Were we wrongfully denied? While our flights were fine, the connecting experience was immensely disappointing and made for a sour end to our trip.
I am a One World elite so was not able to experience Delta One until recently. They may have been last of the Big 3 domestically but it really delivered. Visited JFK and LAX with the edge for me going to LAX.
If you go to DL's website, they show a somewhat earlier opening in SEA, and a much earlier time for BOS. I won't post those times in case I got an rouge page at their dite. But it clearly referred to the D1 clubs.
I have viewed two inconsistent times a DL's website for the BOS D1 lounge. I'm guessing the one agreeing with Ben's post is right. The other has a much earlier opening.
Locations
UAL: (6) EWR, IAD, ORD, IAH, SFO, LAX
AAL: (6) JFK, PHL, MIA, ORD, DFW, LAX
DAL: (4) BOS, JFK, SEA, LAX
Hubs without
UAL: (1) DEN
AAL: (2) CLT, PHX
DAL: (4) ATL, DTW, MSP, SLC
So, what you’re saying is… United Polaris an American Flagship may have more quantity.
But, from experience, and having been to many with each, Delta One is better quality, and they are catching up quickly in number.
Catching up quickly? 2028 at the earliest for ATL and no plans for three other hubs? Looks like D1 Clubs come about as fast as D1 aircraft renovations. AUS might beat ATL.
Btw, HAPPY BIRTHDAY Ben!
Last week, I visited my fourth D1 Lounge---BOS. It was definitely more of a restaurant than a lounge; but the Terminal E Sky Club next door is one of the better Sky Clubs out there, IMO. The menu is arguably the best among the four D1 Lounges, especially if you like seafoods. However, if you are connecting on a domestic flight departing from Terminal A, do leave AMPLE time for traveling to Terminal A; I...

The menu is arguably the best among the four D1 Lounges, especially if you like seafoods. However, if you are connecting on a domestic flight departing from Terminal A, do leave AMPLE time for traveling to Terminal A; I would say at least 20 to 30 minutes. Also, the shuttle bus leaves from E13, right across from the stairs when you exit the lounge. The DL app gave me wrong directions!!!
Overall, I like the JFK D1 Lounge the most. In the past, I would avoid connecting in JFK for my European trips. Now, I don't mind. :-)
BOS D1 does have excellent CHOWDAH!
Ben, I believe your SEA lounge opening times are not correct for the summer season. It will be open till about 9pm for the summer as the SEA-LHR flight will be seasonally rescheduled to depart much later.
Actually open until 1030pm. I used it last week for my 945pm flight to London
If I am flying JFK to Toronto in Delta Y and connecting to a Virgin Atlantic J flight the same day, would I get access to the D1 Lounge at JFK? Rules seem to suggest yes. TIA!
Yes, D1 for VS in J to LHR; if not, Clubhouse at JFK T4 is ok, but D1 is clearly better.
By the book you should but in reality you will be directed to the VS Clubhouse, I was flying DL - F to IAD then VS J to LHR and was denied access.
Thanks! For the heads up! Probably won’t show up too early then!
Wow, that’s really lame that they denied you. They’re clearly playing by their own rules at T4…
JFK, LAX, and BOS are awesome. Still need to make it to SEA, and looking forward to the rest, once opened. Wild that the Atlanta headquartered airline has waited so long before opening one at ATL. Perhaps, it's because they have a fortress hub there, and do not feel like they need to compete. *drops fishing line into the water* (come, Timmy Timmy Timmy...)
The reason it’s taking so long for ATL is because they don’t have a ready-to-move-in space at either Concourse E or F (the only two concourses that would have D1 long haul international flights). That being said, plans are now underway for the ATL lounge; vendor bidding has already started.
Rylan, that's good to hear, and long-overdue. For ATL, clearly, it should be at the International Terminal (F) or E, since most of the qualifying flights are based from there.
I've been to LAX and SEA. The SEA one is nice, especially the outdoor terrace with views of Mount Rainer (though it can be noisy out there). Certainly prefer the LAX location.
D1 lounges might be the only US based J lounge I'd put some effort into spending time in (not that Polaris or Flagship lounges are bad, but D1 is certainly better quality).
AA/BA's Chelsea and Soho at JFK T8 are decent, too.
My understanding is that the lack of D1 lounge access on KL & AF in BOS is based on whose metal it is. So, you can have a flight with a DL code-share number bought from DL in business. But if flown by AF/KL, it won't show as D1 on the ticket, and you won't have D1 lounge access.
But.... You'll have access to the BOS AF/KL lounge which is at least on par with DL's, and better in several aspects. It looks like that lounge was built (in 2025) specifically to accomodate the AF/KL passengers dumped by Delta
Given AF's unforgiving nature, I wonder where they are giving Delta a taste of their own medicine. In CDG, Delta passengers can use the 3 AF lounges in Terminal 2E. Delta's only other destination in...

Given AF's unforgiving nature, I wonder where they are giving Delta a taste of their own medicine. In CDG, Delta passengers can use the 3 AF lounges in Terminal 2E. Delta's only other destination in France is Nice (1 flight daily) where AF has a lounge, not a particularly plush one as AF has none to few long distance flights out of NCE. I would assume that this is the lounge used by Delta.
The AF/KLM lounge at Logan is pitiful. I don't think anyone who has been to both lounges at Logan would ever think about calling them comparable. It's window-less and very basic. In 2025 they put some marginal upgrades into the finishes, but it was far from a full overhaul. The regular Skyclub in Terminal E is far superior to the AF lounge.

The Boston D1 lounge is one of the best dining experiences in a US lounge. The fact that Delta can't figure out how to allow passengers from AF/KLM J metal into it, is frankly pathetic. That's, by and large, 3 extra flights a day - 2 AF and 1 KLM. They have no problem letting J passengers on Virgin, Korean, and SAS access it. Most days the pricing on Delta One vs. AF/KLM Business is the same; Delta needs to do better.
"Most days the pricing on Delta One vs. AF/KLM Business is the same; Delta needs to do better." When I book the cost from home-DLHub-CDG-destination is always about the same. Going through BOS has the terminal switch pain. But. If you do it, why would you take DL in a 333/339 vs. a 350 on AF? Plus, you get EU261 coverage to CDG. Oh, says DL, you wont get D1 access in BOS if you...

Oh, says DL, you wont get D1 access in BOS if you use the codeshare. Well, the only other D1 club existing east of Montana is JFK, which you can use on an AF code share. But, go through JFK if you can avoid it?
Thanks, I'll look at the AF lounge at BOS. I wasn't impressed when I used their lounge there last time, but that was before DL had an E concourse lounge of its own. I note PP members have access to it until 2:30, so I'm concerned about capacity issues.
