The issue here is that AJAX is asynchronous. The the moment you're
checking pnrexists(ph), it'll execute the AJAX but nothing is returned
"at that moment" (which means it is not-true, so the if-statement
fails). Then a few milliseconds later, your AJAX response has
returned, but the code is way passed the if-statement by then already.
Try adding the 'async: true' to the $.ajax() option. This tells the
rest if your code to wait for the AJAX response before continuing.
