Yeah the online system won't allow updates. I applied about a year ago; don't currently know anyone there.
I did manage to send in an update but I had to re-register with a new email addy to do so. I would hope that HR is painfully aware of the limitations of their system as the code is currently written. Sometimes it would seem that the old paper app system was better but I am sure there are benefits to the electronic process that aren't clear to those on this side of the equation.
I'm flying corporate now, prior 121 time. Not a clue how I would meet a Spirit guy/gal, let alone get an internal rec.
