Delta One Review: The Best Cabin at the Worst Price
Delta One scores a perfect 10 on seat and a perfect 10 on IFE — one of only two carriers in our data to do both. It also carries a $3,797 median business premium, the highest we price, and scores 0 on Value.
Best for: Anyone weighing Delta One against United Polaris, or wondering whether a better seat is worth a four-figure premium

Delta One is the best-equipped business cabin in our data, and Delta is the most expensive airline to Europe in our data. Both statements come from the same grid, and the second one is why the score is not higher.
The scores
Our score

- Lounge

- 0
Scored against our published rubric.
7.5 out of 10. Three perfect tens and a zero.
That is not a rounding artifact or a quirk of the rubric. Delta scores a full 10 on seat, a full 10 on IFE and a full 10 on lounge and baggage entitlement — and 0 on Value, because Value is computed from what it charges against every other carrier on the same route in the same week.
Only two carriers in our data score 10 on both seat and IFE: Delta and JetBlue. Only two score 0 on Value: Delta and Virgin Atlantic. Delta is on both lists.
The hardware is genuinely excellent
| Aircraft | Seat | IFE | Lounge & bags | Value | Product |
|---|---|---|---|---|---|
| 767-300ER | 8 | 10 | 10 | 0 | 7 |
| A350 / A330-900 (Delta One Suite) | 10 | 10 | 10 | 0 | 7.5 |
Same 1-2-1 lie-flat, no privacy door.
The 767-300ER runs the same 1-2-1 lie-flat without a privacy door. Every Delta One aircraft keeps direct aisle access, so the variation is the door rather than the seat.
Our seat score is lie-flat (five points), direct aisle access from every seat (three), and a closing door (two). The Delta One Suite takes all three.
The variation between Delta's two cabins is unusually mild, and worth saying clearly because it runs the opposite way from most carriers on this site. Every Delta One aircraft is 1-2-1 with direct aisle access — the 767-300ER simply lacks the door, and scores 8 instead of 10. Compare that to Lufthansa, where the gap between cabins is five points and the worse one makes you climb over a stranger, or SWISS, where every seat does. Delta's floor is high.
The IFE 10 is rarer than the seat. It needs a seatback screen, power, and free wifi — and free wifi is the part almost nobody offers. We record wifi as paid unless free was independently established, deliberately, because a wrong "free" adds two points that end up inside Review structured data. Delta and JetBlue are the only carriers that cleared it.
And then the fare
$3,797. That is Delta's median premium above the cheapest option, across 231 business routes.
One carrier prices higher — Virgin Atlantic, at $3,928 — but on 12 routes against Delta's 231. A median is only as trustworthy as the coverage behind it, and on that basis Delta is the most expensive business carrier of any real scale in our data.
| Carrier | Product score | Business routes | Median premium |
|---|---|---|---|
| Aeromexico | not verified | 59 | $391 |
| SAS | 8.3 | 152 | $1,016 |
| Air Europa | 8.3 | 28 | $1,052 |
| Air France | 8 | 208 | $2,339 |
| KLM | 7.5 | 200 | $3,001 |
| Delta | 7.5 | 231 | $3,797 |
| Virgin Atlantic | 7 | 12 | $3,928 |
Value is scored on that premium, and a zero is what a premium that size produces. It is worth being precise about what the score means: it does not say Delta is bad, it says that on a typical route Delta flies, a business ticket costs materially more than the alternatives selling the same week.
Whether that is worth it is a judgment we are not making for you. What we will say is that the gap is four figures, and a door on your suite is not usually a four-figure decision.
Economy is expensive too
This is where Delta's reputation and our data diverge most sharply.
In economy Delta carries a $278 median premium across 268 routes, scoring 3 out of 10 on Value and ranking number 29 of 31 carriers on price. It is the outright cheapest carrier on 58 routes, which sounds better than it is against 268 priced.

The reach is real — Delta prices from more US cities than almost any carrier here, and that is worth something if you live somewhere the European flag carriers do not sell. But reach is not price, and on price Delta is near the bottom of both grids.
The shape of Delta's network is the real trade-off
There is a structural difference between US and European carriers that decides whether an airline can serve you at all, and it shows up clearly once every carrier is priced from all 26 gateways.
| Carrier | US cities | European cities | Routes | Shape |
|---|---|---|---|---|
| JetBlue | 14 | 2 | 21 | wide in the US |
| American | 26 | 13 | 247 | wide in the US |
| Delta | 25 | 15 | 268 | wide in the US |
| United | 25 | 17 | 317 | wide in the US |
| Air Canada | 22 | 15 | 129 | wide in the US |
| ITA Airways | 5 | 8 | 25 | wide in Europe |
| British Airways | 21 | 34 | 491 | wide in Europe |
| Aer Lingus | 11 | 18 | 74 | wide in Europe |
| Icelandair | 10 | 20 | 150 | wide in Europe |
| Lufthansa | 14 | 29 | 292 | wide in Europe |
| Turkish Airlines | 13 | 35 | 301 | wide in Europe |
| KLM | 11 | 32 | 217 | wide in Europe |
| Air France | 11 | 33 | 216 | wide in Europe |
| Iberia | 6 | 21 | 62 | wide in Europe |
| SWISS | 7 | 26 | 129 | wide in Europe |
| Royal Air Maroc | 4 | 16 | 38 | wide in Europe |
| SAS | 7 | 30 | 170 | wide in Europe |
| Finnair | 3 | 16 | 36 | wide in Europe |
| Austrian | 2 | 11 | 20 | wide in Europe |
| TAP Air Portugal | 5 | 28 | 131 | wide in Europe |
US carriers are wide in America and narrow in Europe. European carriers are the mirror image. Delta sells 25 US cities into 15 European ones. TAP sells 5 US cities into 28. Neither shape is better — they fail different readers.
If you live somewhere the European flag carriers simply do not fly from — Nashville, Salt Lake City, San Diego, Raleigh — then Delta, United and American are frequently the only airlines selling you a single-carrier ticket at all, and the premium is partly the price of that. If you live in Boston or New York, where a dozen carriers compete, you are paying it for nothing.
That is the honest case for Delta's fare, and it is a narrower one than the fare implies. British Airways manages 21 US cities and 34 European ones at once, which is why it prices more routes than anyone else in our grid.
Delta One against United Polaris
The comparison most readers actually want, and one this site has published four different answers to across five business-fare collections. With the grid complete, the answer is stable:
United takes it, 8 to 7.5.
Delta has the better seat — 10 against United's 8 — and much better screens. It loses on the fourth dimension: $1,723 median premium against $3,797, and a Value score of 6 against 0.
If you are spending points rather than cash, that reverses — see below.
Where points change the answer
Delta is a SkyTeam carrier. The programs that reach it are Flying Blue, Virgin Atlantic and Delta SkyMiles itself.
The single most useful thing on this page for a points traveler: Virgin Atlantic Flying Club books Delta One as a partner award, and it is our highest-scored transfer destination — Amex to Virgin scores 88 of 100 for Europe. Transferring to SkyMiles directly is usually the more expensive route to the identical seat, which is why we score Amex to Delta at 48 against Virgin's 88.
And Delta is the clearest case on the site of a cash fare flattering an award. A $3,797 premium means almost any redemption looks spectacular measured against it. That is the arithmetic behind most published points valuations, and we take it apart here.
The verdict
If someone else is paying, or you are paying in points, Delta One is among the best ways to cross the Atlantic — a 1-2-1 suite with a door, free wifi, and a floor high enough that even the older aircraft keeps direct aisle access.
If you are paying cash for it, you are paying the highest premium of any carrier at scale in our data for a seat whose nearest competitor costs $1,723 less at the median and scores higher overall. This site exists for people making the second kind of decision, and for them the answer is usually United, Turkish, or an award booking.
The seat is excellent. It is not $3,797 excellent.
Common questions
- Is Delta One worth it to Europe?
- As hardware, it is close to the best we have verified: a full 10 on seat for a 1-2-1 suite with a door and direct aisle access, and a full 10 on IFE, which only Delta and JetBlue achieve because only they offer free wifi alongside a seatback screen and power. As a purchase it is the hardest to defend on this site. Delta carries a $3,797 median business premium across 231 routes — the highest of any carrier we price — which scores 0 out of 10 on Value and drags the overall product score to 7.5.
- Is Delta One better than United Polaris?
- Delta has the better seat and much better screens; United wins the comparison anyway, 8 to 7.5, because Value is one of the four dimensions we can verify and Delta scores 0 on it against United's 6. United's median business premium is $1,723 against Delta's $3,797. Our full head-to-head goes through it route by route.
- Is Delta expensive to Europe?
- In both cabins, yes. In economy it carries a $278 median premium across 268 routes, scoring 3 out of 10 on Value and ranking number 29 of 31 carriers on price. In business the median premium is $3,797 across 231 routes. Only Virgin Atlantic prices higher in either cabin, and it does so on 12 routes against Delta's hundreds — so Delta is the most expensive transatlantic carrier of any real scale we price.
- Do all Delta One seats have a door?
- No. The A350 and A330-900 have the Delta One Suite with a closing door and score 10 on seat. The 767-300ER runs the same 1-2-1 lie-flat layout without a door and scores 8. Every Delta One aircraft keeps direct aisle access from every seat, so unlike most carriers the variation here is the door rather than whether you climb over someone — a much smaller gap than the one Lufthansa or SWISS passengers face.
- Have you flown Delta One?
- Yes, in business on a Europe route, which is why this is labeled Flown rather than Researched. Service, food and ground recovery are still unscored, as they are in every review here — they cannot be read off a specification, and the four dimensions below are the ones that can.
