Frequently asked questions
- How do I track my 21 Air flight?
- Enter the flight number at the top of this page, for example 2I1234. You will see the status, expected time, gate and terminal. If the aircraft is airborne right now, it also appears on the map above.
- What do 2I and CSB mean?
- 2I is the code on your ticket and in the flight number. CSB is the callsign the crew uses on the radio and the code the aircraft shows on radar.
- Does 21 Air fly to Puerto Rico?
- Yes. 21 Air has 2 connections to Puerto Rico, making it the best-served country outside its home market. The route map above shows exactly which ones.
- Which airlines fly the same routes as 21 Air?
- On 35 connections you will also find ABX Air, on 21 Delta Air Lines and on 20 Air Transport International. Useful if you are looking for an alternative on the same route.
- My flight is not on the map. Why not?
- The map shows aircraft that are airborne right now and broadcasting their position. An aircraft still at the gate or just landed broadcasts nothing and will not appear. Coverage matters too: positions come from volunteer-run ADS-B receivers, and there are gaps over oceans and sparsely populated regions. Search by flight number instead: that page works even when the aircraft is on the ground or briefly out of range.
- Where does this data come from?
- Connections are derived from observed callsign routes and are not an official schedule: they say nothing about which days a route operates. Positions on the map come from ADS-B receivers. Flight status, gate and terminal come from the airports themselves.
Route source
Hubs, destinations and the route map come from the flight archive (ADS-B, adsb.lol): what this airline actually flew from October 2025 to September 2026, counted per route per month by callsign. We do not see every flight, so this is a floor. Updated on October 6, 2026.
These routes come from the flight archive (ADS-B, adsb.lol): what actually flew over the last twelve full months, counted per route per month by callsign. Not a timetable: we do not see every flight, and a listed route does not guarantee a currently bookable flight.
