3 SWA's to IWA on Monday, Where are they?

I read several accounts about 3 SWA flights that diverted to IWA
due to wind shear issues at Sky Harbor, Why can’t I find them on IWA’s arrival log?

Probably because the flight plans didn’t make it into the national system.

I did find 3 departures from IWA to PHX for Southwest:
SWA627
SWA1120
SWA1460

If you click on the links above, you’ll see that the previous flight is the flight to PHX (you’ll need to click on the “more flights” link to see the previous flight). It appears that they tried to land at PHX. The ATC marked them as “arrived” at PHX then they flew to IWA without a flight plan being entered into the national system.
