Well, websites aren`t always updated immediately, so that could be the reason.Also, it`s much easier just to send out an ad.
It doesn`t mention anything about the pay (besides the usual "competitive salary" and "benefits"), nor about the bases, but if I had their requirements (or close to them) I would definitely send an application.I`m sure some of the SAS pilots are doing this as we speak.
Good luck to those who try!
