Flightaware is not tracking sky west flights tonight. for example flight 4770 from LAX tp PHX says taxing pushed from the gate xx minutes ago. While Delta and flight stats show it in flight. Acording to flightstats.com at 9:30 its 130 miles from LAX and 241 miles from PHX. Flighttracker says its taxing.
Looks like it operates as a different flight number - flightaware.com/live/flight/SKW4 … /KLAX/KPHX
The flight finder (flightaware.com/live/findflight/KLAX/KPHX) is a good tool for finding the actual flight number.
