Delta One Lounge access goes to travelers with a same-day Delta One ticket, departing or arriving, and to Delta 360° Members on a same-day Delta First ticket, excluding Delta First Basic. Select partner premium cabins get in too, and Delta 360° Members can pay for guests.
The partner list is specific: Air France La Premiere and long-haul Business, KLM Business, Korean Air First and Prestige, LATAM Premium Business, and Virgin Atlantic Upper Class, on a same-day departing or connecting flight. Delta sends Air France and KLM Business passengers in Boston to other lounges. Sky Club membership and credit cards don't get you in, and Basic Business loses access for travel on or after January 19, 2027.
Delta says day passes and lounge memberships aren't available for purchase. With one narrow exception covered below, the only way in is a same-day ticket in the right cabin.
This guide covers where the lounges are and when they open, exactly who gets in, the restriction that takes effect in January 2027, and what to do if you're flying Delta and this door is closed to you. The rules, hours and amenities below come from Delta's own Delta One Lounge page, read on October 10, 2026.
Where They Are and When They Open
Delta lists Delta One Lounges at four airports: JFK, LAX, BOS and SEA. Here's where Delta places each one and the hours it gives:
- New York (JFK): Terminal 4, between Concourses A and B, next to the main security checkpoint (what's inside the Delta One Lounge at JFK). Open daily 4:30am to 11:00pm, with the Brasserie restaurant serving from 11:00am to 9:30pm.
- Los Angeles (LAX): Delta lists two locations. Terminal 3, across from the Food Court, is open daily 4:15am to 11:30pm. Terminal 2, Mezzanine Level, is open daily 7:00am to 11:00pm.
- Boston (BOS): Terminal E near Gate 13, entered through the E13 Delta Sky Club. Open daily 12:00pm to 10:45pm.
- Seattle (SEA): Concourse A near Gate 11, on the upper level of the A11 Delta Sky Club. Open daily 8:00am to 9:30pm.
Hours change, so check Delta's page under each airport's tab on the day rather than trusting any third-party description, including this one.
The physical relationship at Boston and Seattle is worth noticing because it's easy to misread on arrival: at Boston you enter the Delta One Lounge through a Sky Club, and at Seattle it's on the Sky Club's upper level. Two different lounges with two different access rules, under one roof.
Who Actually Gets In
Delta's access policy lists the qualifying routes in, and the wording matters more than a summary of it.
A same-day Delta One ticket. In Delta's words, "a ticket containing one or more flights operated by Delta including a seat assignment in the Delta One class of service in the direction of travel." Departing or arriving both count, so you can use the lounge after a Delta One flight as well as before one.
A complimentary upgrade to Delta One. Delta's FAQ says you're eligible "if you have a confirmed Delta One seat at time of Delta One Lounge check-in."
Delta 360° Members flying Delta First Class. Delta 360° Members get in on a same-day departing or arriving Delta First Class ticket, "excluding Delta First Basic."
Select eligible partner airline customers in a qualifying premium cabin, on a same-day departing or connecting flight, from the partner list above.
Delta's House Rules add three practical conditions. You need a qualifying boarding pass to reach the secure area, and Delta says gate passes won't be issued for entry. Anyone under 18 needs a responsible, supervising adult. And using a Delta One ticket for the lounge "without good faith intent to fly on the ticketed itinerary" can get you permanently disqualified from both the Delta One Lounge and the Delta Sky Club.
Read what is missing from that list. Delta 360° is the only status tier on it. Delta's House Rules say "other credentials, such as Delta Sky Club membership or qualifying credit cards, cannot be used," and its FAQ answers no to American Express cardholder credentials. That rules out the Delta SkyMiles Reserve card, which opens the Sky Club but not this door.
Delta One Lounge Against Sky Club, on Access Alone
The two lounges are frequently discussed as tiers of one thing. On access they're built on opposite principles, and holding that distinction straight saves a wasted walk.
The Delta Sky Club is a membership network. Delta sells individual and executive memberships, gives Reserve Card Members 15 visits each Medallion Year, and admits travelers in qualifying cabins. That's why so much credit card marketing points at it.
The Delta One Lounge is a cabin amenity. It isn't sold as a day pass or bundled with a card, and Delta 360° is the only status tier Delta names. The ticket is the entry mechanism; the only other way in is as a guest a Delta 360° Member pays for.
The practical consequence: everything you may have learned about getting into a Sky Club transfers to the Delta One Lounge only if it involves a premium-cabin ticket. Membership and card benefits stop at the Sky Club door.
There's one more asymmetry worth knowing, and it runs in the traveler's favor. Delta's Sky Club access rules admit customers ticketed on a same-day domestic Delta One flight, or in Delta One on a same-day international Delta flight. So a Delta One passenger at an airport with no Delta One Lounge can still use a Sky Club where there is one. The reverse never holds: no amount of Sky Club entitlement reaches the Delta One Lounge.
The Rule That Changes in January 2027
One dated restriction is worth putting a marker against, because it isn't yet in effect.
Delta states: "Customers traveling in Basic Business will not have access to the Delta One Lounge for travel on/after January 19th, 2027."
For travel on or after January 19, 2027, Basic Business won't get you in. Our guide to which airlines sell Basic Business fares covers what else that fare leaves out.
If you're booking a Delta One fare for early 2027 and the lounge is part of what you're buying, the fare class is now a thing to check rather than assume.
The Paid-Access Question, Answered
The answer here is narrower than most people expect.
Delta's own FAQ addresses it under a heading asking what happens when a Delta One customer travels with someone in a lower-fare cabin. The answer names who has access, and then permits payment in one case only: "Delta 360° Members traveling in Delta One or Delta First Class may pay to bring in eligible companion guests who may be traveling in a different class of service on a same-day Delta flight." That, too, "excludes Basic fares for travel on/after Jan 19, 2027."
So paid access exists, but it isn't a public product. It's a benefit of Delta 360°, applied to companions rather than to the member. There's no counter where a Sky Club member, a Reserve cardholder or a Diamond Medallion buys a Delta One Lounge entry.
Bringing a Guest
Delta's Companion Guests rule covers Delta 360° Members traveling in Delta One or Delta First, excluding Delta Basic fares for travel on or after January 19, 2027. They may bring their immediate family (spouse or domestic partner and children under 21) or up to two companion guests, for $100 per person or 10,000 of the member's miles per guest. Each guest must be flying on a same-day Delta-operated flight, and children under 2 may accompany an eligible customer at no charge.
For everyone who isn't a Delta 360° Member, the answer follows from the access rules rather than from a separate guest policy: each traveler needs their own qualifying ticket, apart from children under 2, whom Delta lets accompany an eligible customer free. A Delta One passenger traveling with a partner in the main cabin should expect to be admitted alone, so settle it before the trip rather than at the entrance.
Delta's House Rules add operating detail that applies once inside: alcohol isn't served to anyone under 21 and may not be brought in, food and drink may not be taken out, and the wellness area is limited to customers and companion guests aged at least 18, with a liability release to sign before using it. Delta also states that it "reserves the right to revise the House Rules without notice, and the House Rules in effect on the day of your visit will apply."
What Is Actually in There
Delta describes the concept as "world-class dining, indulgent wellness experiences and a new standard of elevated service," which is marketing language, but the specifics underneath it are concrete enough to be useful.
JFK has a 140-seat Brasserie with three-course meal service, plus The Market and Bakery, and a terrace with a retractable roof that Delta says is open 365 days a year. LAX serves sushi and a rotating bento box menu, with nap pods and massage chairs. Seattle has an izakaya dumpling bar, a full-service restaurant and a 270-degree wraparound outdoor terrace facing Mt. Rainier. Boston leans on seafood, including New England chowder. All four list shower suites stocked with Grown Alchemist products.
The distinction that matters against a Sky Club is service model rather than decor. A full-service restaurant with table service is a different proposition from a buffet, and a shower suite is a different proposition from a shower.
If the Door Is Closed to You
Most Delta flyers aren't in Delta One on any given trip, so this is the more useful half of the guide.
The Sky Club is the realistic lounge. It's the network Delta operates at scale, and it's the one that credit cards and status can open. Our Delta Sky Club access guide covers every route in, and the SkyMiles Reserve card review covers the card most often bought for it.
Check whether your airport has a better non-Delta option. At several large airports the strongest lounge isn't the airline's. Our ranking of LAX lounges works through one airport in detail, and the best credit cards with lounge access covers which networks reach which terminals. For Delta's hubs, our lists of Minneapolis Airport lounges, Salt Lake City lounges and Cincinnati Airport lounges show the other options.
Don't buy a premium card for this lounge. No card grants Delta One Lounge access, so a card bought for that reason returns nothing. If lounge access generally is the goal, the Amex Platinum and Capital One Venture X reach far larger networks, and our Chase and Amex comparison sets their lounge networks against each other.
How to Actually End Up in One
Three honest routes.
Book Delta One for a long-haul trip you were taking anyway. The lounge is a component of a premium-cabin fare, so the decision is really about the cabin. Our guide to the Delta SkyMiles program covers redeeming miles for that cabin.
Fly a partner airline's qualifying premium cabin through one of the four airports. Delta's policy admits select partner customers in a qualifying premium cabin, which widens the entry beyond Delta metal.
Arrive, rather than depart. A Delta One arrival at JFK, LAX, BOS or SEA carries lounge access on the same day.
Can You Use the Delta One Lounge on Arrival?
Yes. Delta welcomes passengers with a same-day Delta One ticket, "departing or arriving from their flight in the Delta One cabin," to the lounge "while airside in the airport terminal." So plan the visit before you leave the secure area.
Almost nobody plans a lounge visit around landing. Lounges sit in the mental category of things you do before a flight, and the arrivals hall is where people head for the exit.
Three situations where this is worth more than the departure visit:
A long domestic connection after an overnight flight. Say you've landed, you're unwashed, and your onward flight is five hours away. A shower suite and a full-service restaurant make a very different layover from a gate seat.
An early arrival before a hotel check-in. Landing at 7am against a 3pm check-in is a familiar problem with no good answer. The lounge is one, and it costs nothing extra because it's already part of the fare you flew.
A meeting straight off the aircraft. The wellness facilities exist for this, and the alternative is an airport bathroom.
The constraint is the lounge's own hours rather than your ticket, so an early arrival can land before the doors open. Boston doesn't open until 12:00pm and Seattle until 8:00am, so check those two against a morning landing. JFK opens at 4:30am and LAX Terminal 3 at 4:15am.
None of this requires anything beyond the ticket you already flew on. It requires only remembering, on the day, that you're still entitled to walk in.
Before You Go
Four things worth confirming before you fly.
Your fare class, not just your cabin. Basic Business is a Delta One fare that stops working at the lounge door for travel on or after January 19, 2027.
The lounge's hours against your flight. Boston closes at 10:45pm and Seattle at 9:30pm. A late departure can leave you outside a lounge you're entitled to enter.
Whether your companion has their own qualifying ticket. They won't get in on yours unless you're a Delta 360° Member paying for them.
Delta's page on the day. The House Rules can be revised without notice and the ones in force when you visit are the ones that apply, which is Delta's language rather than a hedge of ours.
