Any idea why this flight is being flown under SWA9006?


Looking at that flight number’s history, it looks like they added the KSMF-KPHX leg in the past week. Maybe they changed their minds about it. Also, when I looked at KSMF-KPHX flight finder, I also saw a 9004 from Sunday, and 9005 from Friday.
damiross or TXhorns, any ideas on what the 9000 series flight numbers are used for, besides deliveries perhaps?


We have a few flights like that…it’s more then likely, there is another airlines with the same flight number around the same time, so we file with a 9000 flight number.
