Well, all I can say is keep your head up and don't abandon hope.
Military vet, but not a military aviator; BS degree, CFI and RJ pilot, now a low hour 747 ACMI dawg. 4000'ish hours, less than 1000 TPIC. Never a Check Airman or Chief Pilot. There is apparently a small window for 40 y/o civilians.
After failing to earn an invite to the SWA job fair, I kicked dirt and decided that my name and date of birth combo had driven the algorithm to permanently reject me. After 8 years of applying faithfully to every window, and frequently updating my application - this was near the final straw for me, as I got the reserve job fair notice.
On May 25th I received an interview invite from the April 8th window...an interview invite. I'll be headed to Dallas on June 12th, and options were available for June 12 to 14 both 8am and noon to choose from.
Advice: I am now scrambling to add up hours for every single different airplane I have ever flown, and making all of my individual numbers match my total numbers. This is something you can and should do now. Go get some professional application and resume reviews....and then wait.
Best of luck to those aspiring to go to SWA, I'm humbled by the opportunity and challenge that lies a few days ahead. It is just an interview, but at least its a foot in the door.
