This poll should be separated. Regional/LCC/Cargo/Legacy
Anybody can get a regional interview just by applying.
Job fairs seem to help with LCC interview calls: Spirit, Jetblue, Alaska, Frontier, Allegiant etc, or Cargo places like Atlas, Kalitta
For the big 3 Legacy's I think job fairs are pretty much a complete waste of money for the vast majority of us "regular people" who never hear anything back. Been to major job fairs and the UAL training center ALPA FFD deal. They always make it sound like you are exactly like what they are looking for, and they will surely call. Then you never hear anything. Every Captain I know who has attended these things with a civilian background has had the same experience basically, no matter how good your resume or internal recs are.
Personally, I am done with them and boycotting the whole scheme of having to pay hundreds of dollars to a job fair just to get my resume looked at. I think it's a complete joke and a couple of the popular fairs are just a big money making scheme under the guise of trying to help pilots. They rent out a hotel conference area for a couple days, sell out hundreds of tickets at $100-200+, then they charge the airlines as well. Do the math on what they are making taking advantage of pilots. It can't cost 50+ grand to rent out a 3 star hotel conference room for the weekend, how many tickets did they sell out though at $150? Then the others major fairs you have people sadly pretending to be interested in the cause of Women in Aviation or Obap just to try and get a job, at least that money for those goes to an orginazation trying to help people instead of a straight up for profit business though. It's honestly pretty ridiculous that this is what we have to do these days to get your resume looked at.
I've travelled across the country on limited days off away from home and family/friends, spent a lot of money on these events, waited in line for hours to talk to some of these places and literally get 30 seconds of face time with some of them for all the effort. I always feel ripped off afterwards. We are highly trained, highly experienced, highly educated professionals standing in "take a number" lines in a suit, literally begging for a job, or even an interview. It's freaking sad the industry is this way. You don't see other experienced, highly trained, highly educated professionals wasting their time and money doing this job fair crap. It's an embarrassment.
If the airlines want pilots, they should put on FREE events and have people come and meet with them. At least the ALPA UAL FFD event was free, and it was probably the best one I have attended. At least I got to spend a lot of time with them and I didn't feel ripped off and scammed out of my money.
