There are fairly significant plus' and minus' for both awards. I wish that we could somehow combine the best of both and we would have nirvana. Sigh. Guess that ain't gonna happen.
Blue, I'm not sure what planet you are on, but it isn't the planet Qantas. A 737 FO will earn approximately the same as his 767 bretheren. Certainly not $30K less as you suggest. I know 737 FO's who have earned $160K and others around $125. The average is probably $135. Very similar to 767.
Give me a 767 Brisbane base on the long haul award. Paradise would then only be complete with 70 virgins.
