Thanks for the reply's.
The reason I ask and I probably should have qualified my position earlier. I have been an FO on the 73 for a few years and I have spoken with 76 FO's of similar seniority and more senior (still rotating after more than 3 years on type) than I and in my opinion (and opinions on lifestlye will always be different) is that on the 737 we have much more control over our lives, more days off and go home at the end of the year with more in our pockets. I don't appreciate how the SH award would work for LH ops as I haven't looked into it.
