Delta scores 49 out of 100, which is mixed, and sits 12 of 18 on the board. Nobody publishes per-tail data for this fleet, so this is a number about the airline and nothing narrower. The signed deal below counts zero until hardware flies.

Delta Sync (Viasat + Hughes) on 1,150+ aircraft, free for SkyMiles members, but not fleetwide: the 80 Boeing 717s lost their legacy wifi in May 2026 awaiting the Hughes retrofit, and transpacific widebodies come online fall 2026. Amazon Leo lands on 500 aircraft from 2028.
Delta has Amazon Leo signed from 2028 (Amazon Leo signed for 500 aircraft). ConnectScore counts zero for hardware that is not flying yet, because a deal you cannot connect to is not connectivity.

That is the next-gen number this fleet would carry if the deal lands as announced: 500 of 1,330 aircraft committed × 1.00 low-earth orbit × 1.00 free-for-you. A committed share of the fleet, not a measurement. Amazon Leo has no aircraft in the air, and no passenger has measured it. It is grey by rule, it sorts nothing, and it never appears without the date beside it. All four projections, and the rules →
Every aircraft Delta flies, by system, priced. The rows add up to the published ConnectScore, and the top row on its own is the next-gen number. The build fails if they stop adding up.
| Segment | Aircraft | Share | Share of the fleet | Quality | Free | Points |
|---|---|---|---|---|---|---|
| Viasat or Hughes Delta Sync, free for SkyMiles members. Both systems are modern GEO on the measured numbers, so the unpublished split does not widen the range. Delta's 2H 2025 consistency was 2.2%, the lowest in Ookla's set. Reported Delta news release, 2026-03-31; Hughes/Delta Fusion release, Feb 2025 · 2026-03-31 | 1,150 | 86.5% | 0.55 | 1.00 | 47.6 | |
| legacy GEO or Intelsat inferred INFERRED. The A330/A350 transpacific aircraft Delta says come online “fall 2026”. They carry older service today and Delta does not say which, so the row spans legacy Ku to 2Ku. Reported inferred: Delta's fleet estimate less the Sync count and the 717s · 2026-07 | 100 | 7.5% | 0.22 to 0.55 | 0.85 | 1.4 to 3.5 | |
| no wifi The Boeing 717s. Delta switched off their legacy Intelsat/Gogo units in May 2026 ahead of a Hughes Fusion retrofit, so most of them are flying the summer 2026 schedule with no wifi at all. Reported Delta 717 wifi deactivation, May 2026 · 2026-05 | 80 | 6.0% | 0.00 | 0.00 | 0.0 | |
| ConnectScore We publish the floor. The ceiling is 51, and the gap is the part of the fleet whose split nobody has published. | 1,330 | 100% | 49 to 51 | |||
| Next-gen odds, the top row on its own | 0.0% | 0 |
1,330 aircraft with a published system. Every system on the fleet is named and the counts are not published, so the score is a range. Points are shown to one decimal place; the unrounded rows sum to 48.96, which rounds to the published 49.
Unpublished splits: Viasat or Hughes (1,150 aircraft). Delta news release, 2026-03-31; Hughes/Delta Fusion release, Feb 2025 would settle it. legacy GEO or Intelsat (100 aircraft). inferred: Delta's fleet estimate less the Sync count and the 717s would settle it.
Four things, in the order they become useful. Every one of them is available at tier D, which is the tier this page was derived at. Anything this fleet cannot support has been cut from the list.
Aircraft assignments firm up roughly 48 hours before departure and they can still move up to pushback. Whatever this page says today, the answer for your flight is more settled then.
Delta publishes an amenity marker against each flight in its own booking flow, and that marker is about the aircraft now assigned to it. It is the closest thing to a per-flight answer this fleet has. The airline is asserting it; nobody has verified the install.
Nobody has load-tested a full cabin on any of these systems, so a good score is not a promise about the hour you fly. Downloading the deck is the move that makes the odds stop mattering.
Delta offers Viasat fleetwide as of 2026-07. Its ConnectScore is 49 out of 100, in the mixed band.
On Delta it is free onboard. ConnectScore multiplies the fleet share by a free-for-you factor, so a paid or unconfirmed free claim scores lower than the same fleet given away free.
The whole fleet, per the airline. Compiled from public airline announcements, July 2026.
Everything on this page comes from what Delta has published about its own fleet. Nobody has published what it was like in the seat. If you flew Delta this month, thirty seconds here is a data point nobody else has.
