The following companies seem to be in the wrong ‘filter’ - they show up under ‘General Aviation’ instead of ‘Airline’ when looking at departures
flightaware.com/live/flight/GJS5693 - Example for GoJet
flightaware.com/live/flight/TAI581 - Example for TACA
flightaware.com/live/flight/ANA1 - Example for ANA
flightaware.com/live/flight/AUA94 - Example for Austrian Air
Other overseas carriers seem to work - AFR for Air France, VIR for Virgin, etc.
