Use the airline's ICAO callsign, not its two-letter ticket code. BA117 may broadcast as BAW117; operational callsigns can differ. We never guess a match.
Skyglass is a public preview by Rendell. Aircraft positions come from volunteer ADS-B receivers via adsb.lol, under the Open Database License. Map © OpenStreetMap contributors. Mapping library: Leaflet (BSD-2-Clause).
Receiver coverage is incomplete, especially over oceans and at low altitude. Data can be delayed or wrong. We refresh every 30 seconds while this page is visible, with a short shared cache. Each aircraft shows the age of its last position. We do not extrapolate movement.
Save flight numbers and dates as personal plans, then look up an exact broadcast callsign across the feed. A callsign may be reused or differ from your ticket. There are no verified airline schedules, delays, gates, cancellations, arrival estimates or push alerts in this preview. No result means no observation, not a cancelled flight.
Flight plans stay in this browser's local storage and do not sync. Clearing browser data removes them; export a backup first. Your last search area and radius are also saved on this device, not a location history. Optional location access is requested only after you tap the button. Search coordinates are rounded to roughly a kilometre before being sent to our Cloudflare service and adsb.lol. Map tiles are requested from OpenStreetMap, which receives your IP and map area. Callsign searches pass through our service to adsb.lol. No accounts, mail or calendar access. Cloudflare provides hosting and security checks and may set a security clearance cookie. This site’s existing Cloudflare Web Analytics measures visits and page performance; flight plans remain in your browser. See Cloudflare’s privacy policy.
