Reserves are required to cover all 320 flying, not just SQ stuff.

And the big allure to the international flying at AA UA and DL is the widebody pay rates, but the SQ flying is just the regular 320 pay scales plus the $4 international override.

​​Supposedly a bunch of new hires just got SQ in training, so I'm sure anyone sho wanted it on the Supplental Bid got it.
