Question 1

Which IAD to SXM flights have Starlink WiFi?

Accepted Answer

No confirmed Starlink flights are currently tracked on the IAD–SXM route. Some airlines have announced Starlink but have not yet equipped aircraft serving this route.

Question 2

Does the IAD–SXM route have Starlink?

Accepted Answer

Route-level Starlink coverage shows the percentage of an airline's fleet equipped with Starlink — not a guarantee for a specific flight. Even on a high-coverage route, the actual aircraft assigned on the day of travel determines whether Starlink is on board. Search by specific flight number on StarlinkFlights for a per-flight confidence score.

Question 3

How do I find a Starlink flight from IAD to SXM?

Accepted Answer

Search your specific flight number on StarlinkFlights (for example, "UA346"). Our confidence engine checks the aircraft assigned to that flight against our proprietary aircraft database, giving you a probability score before you board. You can also browse individual airline pages to see which operators fly Starlink-equipped aircraft most frequently.
