The ADS-B network is not responding, so this page found nothing — that is a fault at our end and says nothing about how many Frontier Airlines aircraft are flying. It normally clears within a few minutes.
How this page finds Frontier Airlines aircraft
There is no way to ask the ADS-B network for “every Frontier Airlines aircraft” — the network reports by position, not by operator. So this page looks around the airline's busiest airports and keeps the aircraft whose callsign begins FFT. Right now it scanned DEN, TTN, CUN and ILG.
This is a sample, not the whole fleet. Aircraft over oceans, between those airports, or outside volunteer receiver coverage will not appear here even though they are flying. A short list does not mean a small airline.
