All of those numbers include the planned step increase so actual changes since 2011 is plus 0.5%. I don't view a step for experience that is in my contract as a rise.
If you want to really see how we have done the pay of a starter was as follows:
1992 - 15500 (75 hrs)
2014 - 29000 (85hrs)
So about doubled in 22 years. From 92 to 2000 official inflation was 52%. From 2000 to 2014 73%. The peak was nearly 15% in just 2008 which about matches all the pay rises since 07. (I believe "ex-pat inflation" is much higher)
So 15500 in 92 should be 46192 AED with no erosion! (Adjusted for official inflation and extra hours flown)
