How to read a Spirit Airlines flight number

Every Spirit Airlines flight number starts with NK, 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 NKS, and controllers address it as "Spirit Wings". One thing to watch: codeshares. A ticket sold by another airline can be operated by Spirit Airlines 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.
