I believe those payrates are US$. Flat pay is for 2 yrs. After that you enter a "wage pool" which is calculated monthly and therefore varies but averages out to $60-70k/yr.
At the company's discretion you may be frozen for up to 5 yrs on your assigned initial position which will be A340/B767 relief pilot or Emb 170/190 FO ( the CRJ is leaving). You are in the wage pool untill you are awarded a higher-paying position i.e A320 FO.
There are two equipment bids per year, typically spring and fall and is awarded by seniority of course.
Per diems average $7-10k per year depending on equipment and is of course tax free.All in all not bad if you consider the long term benefits but things sure are not as good as it use to be.
