That EBA was negotiated by the Short Haul Pilots Council and AIPA was not allowed to have any input into the EBA (although they did have "observer" status at some meetings). AIPA did privately advise the SHPC about the ramifications of the proposed "B" scale but the anger that the AA pilots had against QF pilots was so intense that this advice was ignored and they took the pay rise at the expense of the future F/O's that they were to fly with. Qantas management just watched this ludicrous situation and laughed all the way to the bank. As mentioned previously, they had the opportunity 2-3 years ago to redress this situation but as they had to give up a small percentage of their pay, they voted against it. These B737 captains are of course paid more than B767 captains.
G'burg - I agree with Keg. I see no connection between this situation and the DJ pay scales.
