If you are having issues with the online application, you can always try this trick. Re-register a new user. You have to use a new email address. Let me know if that helps.

PS - I did stand-ups in the US. I worked at a regional flying turboprops. These rosters (at flydubai) are worse. Hopefully they are addressing it with PBS, but take heed of the warnings. Our COO is now in fix-it mode and has met with the guys from AIMS recently about the implementation process of PBS, so it is more than a rumor.
