About inair.online

inair.online answers a simple question: for my upcoming travel, which flight is most likely to have Starlink? It's built to quickly & easily inform your booking decision.

inair.online is a free tool built by Evan. Evan also builds Taya Flights, a flight logging and mapping app.

Search any route between US airports (50 states plus Puerto Rico, the US Virgin Islands, Guam, the Northern Mariana Islands, and American Samoa), or any flight operated by a US carrier. Checking a United flight from Denver to Calgary works the same as a United flight from SFO to LAX.

Different signals matter at different distances from the flight.

1. Aircraft lookup. Within roughly 48 hours of departure, the airline has usually assigned a specific aircraft. We check whether that aircraft has Starlink installed. Today only United (with its regional partners), Alaska (now including Hawaiian), and JSX have any Starlink-equipped aircraft — those are the carriers a yes-or-no answer is possible for at this step.
2. Fleet share. For close-in flights — whether or not an aircraft has been assigned — we look at how many of that carrier's aircraft of the assigned type currently have Starlink. Aircraft swaps happen, so a transparent share like “12 of 48 United 737 MAX 9s have Starlink” gives a more honest picture than yes/no on its own.
3. Forecast. For flights further out, today's installs don't tell the full story. We project ahead from announced rollout schedules so a flight months away reflects expected progress. A Southwest flight in October 2026 may well have Starlink given their announced summer 2026 launch, even though they don't yet have Starlink live on any aircraft. Carriers without announced Starlink rollouts (American, JetBlue, Frontier, Spirit, etc.) stay at “no Starlink yet.” Delta and JetBlue have separately selected Amazon Leo, but no Leo aircraft are flying yet and installs aren't expected until late 2027 — we'll fold predictions in once timelines firm up.

Flights on non-US carriers currently return “Unknown” but will be supported soon.

The forecast layer is what gives a flight months out a different answer than today's snapshot.

Thresholds per carrier and aircraft type come from public sources — airline earnings calls, press releases, supplier type-certificate filings, and tracked install pace. They're estimates, deliberately conservative, and reviewed regularly.

Per-aircraft Starlink status is built from public airline records, regulatory aircraft registries, operator-curated sources, and operational signals such as aircraft taken out of service for retrofit. New installs and aircraft retirements flow through an ongoing review and validation process so each prediction reflects our best current understanding.

• Schedule horizon. Most airlines publish schedules 11 months into the future (and 8-9 months for Southwest). Beyond that we can't answer.
• Aircraft swaps happen. Even with an aircraft assigned, airlines re-assign equipment up to the day of the flight. Treat aircraft-specific answers inside 48 hours as “most likely,” not guaranteed.
• Aircraft-type sub-variants. Some carriers install Starlink on certain interior configurations of a type before others. We don't always have the data to split within a type, so the fleet share is a type-wide average.
• Schedule changes. Schedules are updated continuously by the airlines. A flight that exists today may not exist by the time you fly, or may be reassigned to a different aircraft type.

Starlink is at an inflection point for US commercial aviation. The quality difference between Starlink and the legacy geo-satellite systems most aircraft still carry is large enough that it changes how a long flight feels — and rollouts are moving fast enough that the answer for a flight months out can look very different from a flight today.

Does my specific flight have Starlink?

Search the flight number or route on the inair.online homepage, optionally with a date up to 11 months ahead. Each result shows a category (likely / possible / unlikely / no Starlink yet / unknown) and, where applicable, the share of that carrier’s aircraft of that type that have Starlink today.

Which US airlines have Starlink today?

United, Alaska (including Hawaiian), and JSX. Starlink is broadly available on JSX, Hawaiian’s long-haul fleet, and Alaska & United regional jets. United and Alaska are mid-ramp on their mainline narrowbody fleets.

When will Southwest get Starlink?

Southwest has announced a summer 2026 launch with a goal of 300+ aircraft equipped by the end of 2026.

Why does it say “no Starlink yet” for my Delta or American flight?

Delta plans to install Amazon Leo, which will provide a WiFi experience comparable to Starlink, but it is not expected to go live on Delta jets until late 2027 or early 2028. American has not yet announced plans to install either Starlink or Amazon Leo.

Why does it say “Unknown”?

You searched a flight on a non-US airline, or on a cargo airline. We currently track US passenger carriers only — for everyone else, we return “Unknown” rather than guess.

How accurate are predictions for flights months away?

Far-out flights rely on the forecast layer — announced rollout schedules per carrier and aircraft type. Predictions are categorical, not precise probabilities; they’re the answer most likely to still be correct on the day you fly. Aircraft-specific yes/no answers only work inside roughly 48 hours of departure, when the airline has actually assigned a specific aircraft.

Where does the data come from?

Per-aircraft data is built from public airline records, regulatory aircraft registries, operator-curated sources, and operational signals such as aircraft taken out of service for retrofit. Schedule and aircraft-assignment data comes from reliable commercial data sources. Quality is ensured through an ongoing review and validation process.

Does this work for international flights?

Route search works between US airports. Flight-number search works for any flight on a US carrier (including international flights). International carrier coverage is coming soon.

Is this affiliated with Starlink, SpaceX, or any airline?

No. inair.online is an independent project, built and run by Evan alongside Taya Flights.
