There's not really any "magic" number of recommendations. Some guys get hired with a bunch, others don't have any. They are just one piece of the overall system for how they choose candidates. Bill Kennedy did say awhile back at one of the big career fairs that the system won't give you any additional points after 10 recommendations. He also said they are more concerned about someone who can speak to your character than a UA pilot that rode in your jumpseat once. If you know any UA pilots who would write a rec, by all means do it. Also if you meet one that's willing to do it, it won't hurt either. But don't forget that they don't HAVE to be from a UA pilot. They can be from someone who you currently work with who actually knows you well and can speak to your character and work ethic. Again this is scored differently, but definitely doesn't hurt.... With all that said, these observations are based on what BK said and what my experience was. No one who has the exact knowledge of how the system works for picking candidates will disclose that information.
