"@ psa you have a gurantee job at real airline."

That statement is 100% wrong! The great "perk" I mean joke, that you speak of is "preferiental hiring". You are not guaranteed anything...In fact past history has proven that being a PSA or Piedmont pilot is a significant disadvantage of actually setting on property at mainline. You must still interview and get hired. Then PSA management must release you and that requires management to staff the airline properly. Management just released 4 to mainline and "promises" to release 12 more sometime this year. If US Airways is your goal then go somewhere else.
