Guide To Delta One Lounges: Access, Locations, And More

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.

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...)

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.

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.

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.

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.

Actually open until 1030pm. I used it last week for my 945pm flight to London

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 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. 🙂

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!

Btw, HAPPY BIRTHDAY Ben!

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 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.

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.

BOS D1 does have excellent CHOWDAH!

Wow, that’s really lame that they denied you. They’re clearly playing by their own rules at T4…

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.

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.

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.

"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 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?

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.

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.

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 (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.

The timing of the SEA Lounge is all over the place. Some say it closes at 8pm, you say either 4pm or 6pm, and the Delta website says 10:30pm! Which is it?
