Delta One vs United Polaris
America's two premium heavyweights both offer all-aisle-access suites with doors, dedicated lounges and Saks/Someone-branded bedding. The differences are in consistency, lounges and network, and they matter when you're choosing who gets your transatlantic budget.
The verdict
Delta One wins on cabin consistency and the new Delta One Lounges; Polaris wins on network breadth and pre-flight dining. On any given route, the deciding factor should be aircraft type and the negotiated fare, which is exactly what your advisor compares.
| Dimension | Delta One | United Polaris | Edge |
|---|---|---|---|
| Seat | Delta One Suite with door (A350/A330neo) | Polaris seat; Studio suites with doors rolling out | Delta One |
| Lounges | New Delta One Lounges (JFK/LAX/BOS) | Polaris Lounges with sit-down dining (5 hubs) | Even |
| Long-haul network | Strong Europe; growing Asia | Largest US long-haul network | United Polaris |
| Consistency | High, most long-haul fleet has suites | Variable until Studio retrofit completes | Delta One |
| Typical negotiated transatlantic fare | $2,600-$4,200 | $2,500-$4,000 | Even |
Travelers, in their own words
What people who flew both actually say
From a flyer who has flown both to Asia and Australia a roughly equal amount:
“Delta food and crew far exceed United! ... IFE is equal. Seats are about equal.”
“The Delta A350 product is far superior to old Polaris, as is DL catering.”
The counterpoint, on United's new Polaris Studio-era cabin:
“Polaris 2.0 is significantly better than D1 on the A350.”
