If you’re hunting for a true “hotel room in the sky” on a U.S. airline in 2025, here’s the short version: yes, you can fly in a fully lie-flat suite with a sliding door on multiple U.S. carriers today—and more are coming. Below is a no-nonsense, human take on what’s actually great, how to find it, and who each product is for.
The quick winners (2025)
- JetBlue Mint Suite (& Mint Studio) — Consistently excellent hard product with a door at every seat on A321LR/A321neo Mint aircraft; Rows 1A/1F are the oversized “Studios.” It’s boutique-feeling and surprisingly attainable with sales. The Points Guy+2One Mile at a Time+2
- Delta One Suite — Stylish, widely available across many long-haul routes. The real suites with doors are on most A350-900s and A330-900neos (but not ex-LATAM A350s; 767-400ER lacks the sliding door). Great network depth. Delta+1
- American Flagship Suite (new 787-9) — Brand-new in 2025 with 51 door-equipped suites per aircraft. Entered service June 5, 2025; now regularly on ORD–LHR with seasonal boosts and further European coverage. The design and tech feel truly next-gen. news.aa.com+1
- Hawaiian “Leihōkū” Suites (787-9) — Every business-class seat is a door-equipped suite. Island vibe, warm crews, and a legitimately competitive hard product; long-haul network is growing under Alaska/Hawaiian. One Mile at a Time+1
- Coming soon: United’s new Polaris with doors — United has unveiled door-equipped Polaris (plus larger Polaris Studio bulkhead suites). First passenger flights targeted for early 2026 (SFO–SIN) as new 787-9s arrive. If you’re a United loyalist, this is worth waiting for. The Points Guy+1
- Alaska (new 787-9 global service) — Alaska is rolling out 787-9s with 34 enclosed suites with privacy doors as it launches a long-haul hub in Seattle; first long-haul operation begins Sept 12 on SEA–ICN, with London Heathrow in 2026. A very new—and promising—option. Alaska Air
What actually makes a great “door suite”?
A door helps, but comfort comes from the whole ecosystem: shoulder room while dining and typing, bed breadth for side-sleepers, storage that doesn’t steal shin space, and seat tech that just works (charging, Bluetooth, lighting). Soft-product consistency—friendly crews, edible food, proactive service—turns “nice seat” into “memorable flight.”
Below, how today’s U.S. options stack up, in plain English.
JetBlue Mint Suite (and Mint Studio): boutique luxury without the attitude
Why you’ll love it: Every Mint seat on the A321LR/A321neo has a sliding door in a 1-1 layout, so you’re never playing footsie with a stranger. The Mint Studio in 1A/1F adds a buddy-seat and more surface area—perfect for couples or work-heavy travelers. Food and service often feel restaurant-grade for a U.S. carrier, and Wi-Fi is fast and free. The Points Guy+2One Mile at a Time+2
Watch-outs: Limited route map versus the Big Three; occasional reports of wear-and-tear or minor seat quirks appear from time to time. Pick Studio only if you’ll use the extra space. The Points Guy
Best for: Travelers who care most about the seat itself and premium cabin vibe on transcon or transatlantic routes (JFK/BOS to London/Amsterdam/Paris, etc.).
How to find it: Look specifically for A321LR or A321neo (Mint) and confirm “Mint Suite/Studio” in the seat map when booking. The Points Guy
Delta One Suite: style, scale, and a big network
Why you’ll love it: The Delta One Suite with a full-height door is found on most A350-900 and all A330-900neo flights, with polished cabins and usually solid bedding and service. It’s the most consistently findable U.S. door suite across lots of cities. Delta
Watch-outs: A few Delta long-haul jets don’t have doors: ex-LATAM A350s and all A330-200/-300s; the 767-400ER has a modified seat without a sliding door. Check the aircraft type before you buy. The Points Guy
Best for: Flyers who value network breadth and want a reliable door suite on popular transatlantic/transpacific routes.
How to find it: Filter for A350-900 or A330-900neo on Delta.com; avoid “A330-200/-300” and be cautious with “A350” if it’s an ex-LATAM tail. Delta
American Airlines Flagship Suite (787-9): the flashy newcomer
Why you’ll love it: American’s new 787-9 debuted June 5, 2025 and packs 51 Flagship Suites with doors—huge capacity for upgrades and awards compared to older jets. The design is crisp, with wireless charging, better storage, and improved premium economy behind it. ORD–LHR sees it regularly, with more Europe flying layered in through the year. news.aa.com+1
Watch-outs: Right now it’s aircraft-specific; older AA widebodies still carry the previous (door-less) business class. Verify you’re on the new 787-9.
Best for: AA loyalists who want cutting-edge hardware and lots of business-class seats (51) to improve upgrade odds. news.aa.com
How to find it: Look for “787-9” and confirm “Flagship Suite” in AA’s seat map. ORD–LHR is the safest bet as of summer/fall 2025. news.aa.com
Hawaiian’s Leihōkū Suites (787-9): island calm, real doors
Why you’ll love it: Hawaiian chose the modern Adient Ascent seat with doors at every suite—no guessing games—wrapped in serene cabin finishes and genuinely warm service. If you’re flying to/from Hawaiʻi or beyond as the long-haul network grows under Alaska/Hawaiian, this is a delightful surprise. One Mile at a Time
Watch-outs: Wi-Fi is still rolling out on the 787; entertainment selection and lounges can feel modest versus mega-carriers (though improving). One Mile at a Time
Best for: Leisure travelers, couples, and honeymooners who still want a top-tier hard product with the door you’re after.
How to find it: Choose flights explicitly operated by Hawaiian 787-9 and look for “Leihōkū Suites” in the booking flow. One Mile at a Time
The near future: United (and Alaska) turn up the heat
- United Polaris with doors — United’s incoming 787-9s get a new Polaris seat with sliding doors plus eight Polaris Studio bulkhead suites with giant 27″ 4K screens, caviar, and an upgraded service script. First routes are slated from SFO in early 2026, beginning with Singapore. If you live in a United hub, this will be a major quality-of-life upgrade. The Points Guy+1
- Alaska’s 787-9 “global experience” — As Alaska/Hawaiian integrate, Alaska is launching SEA–ICN (Sept 12, 2025) and SEA–LHR (daily from 2026) with 34 enclosed suites with privacy doors on the 787-9. It’s early days, but if you’re Seattle-based, that’s big news. Alaska Air
Choosing the right door suite for you
- Solo traveler who wants maximum privacy: JetBlue Mint Suite (any non-Studio seat) or Delta One Suite on A350-900—both feel cocooned without being cramped. The Points Guy+1
- Couples who dine together: JetBlue Mint Studio (Row 1) or United Polaris Studio once live—true buddy seating and more surface area. One Mile at a Time+1
- Upgrade hunters: American’s 787-9 with 51 suites improves your odds; more seats = more last-minute inventory movement. news.aa.com
- Network reliability: Delta’s coverage with A350-900/A330-900neo makes it easier to find a door suite on the route/date you actually need. Delta
- Island trips / West Coast: Hawaiian’s 787-9 brings a door suite to Hawaiʻi-mainland—and it’s legitimately competitive. One Mile at a Time
How to make sure you actually get a door
- Check the aircraft type.
- Delta: A350-900 or A330-900neo (doors). Avoid A330-200/-300; 767-400ER lacks the sliding door. The Points Guy
- American: 787-9 (new config) branded Flagship Suite—don’t assume any 777 or older 787 has doors. news.aa.com
- JetBlue: Look for Mint on A321LR/A321neo and confirm “Suite/Studio” in your seat map. The Points Guy
- Hawaiian: 787-9 guarantees a door suite. One Mile at a Time
- Cross-check the seat map. If the business cabin shows 1-1 (JetBlue) or a staggered 1-2-1 with little door icons (Delta/AA/Hawaiian), you’re set.
- Beware last-minute swaps. If doors are non-negotiable (special trip, honeymoon), aim for routes where your target aircraft is the standard (e.g., AA ORD–LHR on the 787-9, or many Delta A330-900 routes). news.aa.com+1
Final take (as of September 2025)
- Best overall seat experience: JetBlue Mint Suite/Studio. The cabin feels purpose-built to delight, and the privacy is top-tier. If it fits your route, it’s hard to beat. The Points Guy
- Best network with doors today: Delta One Suite on A350-900/A330-900neo. It’s the easiest path to a door suite to the places people fly most. Delta
- Best new hardware: American Flagship Suite on the 787-9. Fresh design, more seats, and momentum on marquee routes—watch this space as more frames arrive. news.aa.com
- Best vibe to/from Hawaiʻi: Hawaiian’s Leihōkū Suites. Calm, stylish, and door-equipped—finally a U.S. island carrier with a truly modern business-class hard product. One Mile at a Time
- What to watch next: United’s door-equipped Polaris (and Studio) begins passenger service in 2026; Alaska’s 787-9 is ramping from Seattle with enclosed suites and new long-haul destinations. The Points Guy+1
