SWA and UPS are tough to get into, no doubt. However, a resume isn't the only factor. I've flown with many guys who have impressive resumes who were rejected from SWA the first time. However, most (not all) of these guys were the types who obviously got into aviation for money and women and have long since been disappointed. A good interviewer can tell whether a person trully loves aviation or is just doing it as a job to pay the bills. In a sea (as it is) of "qualified" applicants, who do you think will get the job?

I've flown with the gruffs who barely run the checklists, recite the responses from memory with me having to actually make sure it is done, A/P is engaged at 500 feet, pax announcements are short, etc. Then I've flown with the guys who still put effort and professionalism into their jobs.

Personality and attitude are most of the battle.
