Cape Air Flight Status
About Cape Air
Cape Air, based in United States, operates under the ICAO code KAP and the IATA code 9K; its radio callsign is "Cair". On this page you can follow Cape Air flights and find the airports it serves.
How to read a Cape Air flight number
Every Cape Air flight number starts with 9K, followed by up to four digits: that is the number on your booking confirmation and boarding pass. In flight plans the same flight carries the ICAO prefix KAP, and controllers address it as "Cair". One thing to watch: codeshares. A ticket sold by another airline can be operated by Cape Air and vice versa; live tracking follows the operating carrier's number, so if your search comes up empty, check the "operated by" line on your booking.

Frequently asked questions about Cape Air
Where is my Cape Air flight right now?
Search the flight number (9K plus digits) in the search box on this page. If the aircraft is airborne within receiver coverage, you will see its live status; before departure you will see the route.
Is my Cape Air flight delayed or cancelled?
Check the flight number on this page for live status, but for rebooking, gate changes and cancellations the airline itself remains the authoritative source.
What do 9K and KAP mean on Cape Air flights?
They are two prefixes for the same airline. 9K is the IATA code you see on tickets; KAP is the ICAO code used in flight plans and by air traffic control.
Does Cape Air operate flights for other airlines?
Codeshare agreements mean a flight sold under another carrier's number may be operated by Cape Air, and the reverse. Live tracking always follows the operating carrier's flight number; check the "operated by" line on your booking.
