I had a meet and greet in October of 2018. Things may have changed since then, but he (chief pilot) then wrote a recommendation that went into my airlineapps after our meeting. I wound up with an interview invite in late February of 2019 and ended up in class in July of 2019. Also of note, I added an additional rec letter from a UA pilot a couple months after the meet and greet, so that may have been what tipped the scales.
I have to imagine the wheels grind somewhat slowly with as many apps hiring has to go through. Hopefully you all get your shot and we can welcome you to class soon!
