FAPA is not a scam. They used to be called FltOps.com but now they are called FAPA. FAPA stands for Future & Active Pilot Advisors. I guess they went back to the old name because it was familiar to older pilots in the airline industry.
You can apply online and hope an airline calls you or you can attend an event and talk directly to the recruiter. You will have about five minutes to show the recruiter why you belong at their airline. The most important thing to bring is a great attitude. The recruiters are looking for motivated individuals who are outgoing and friendly. Make sure you do your homework on airlines you are targeting. Don't forget to network with other pilots at the event. You never know where your next job lead will come from.
If you have any questions about job fairs, send me a PM. We are FAPA's competition. Good luck.
