3. A 15% Red-Eye premium (REP) will be applied to all Red-Eye flights. The REP will be added to the duty period containing red-eye flights. The sum of the duty period credits containing REP will be compared to ADG and THR and will pay the greater.

4. Panama and northern South America (Venezuela, Columbia, Peru, Ecuador) will not be considered Far International for pay purposes for three years after the start of those services. After 3 years they will be considered Far International.

Bottom line is that redeyes don't automatically get a 15% premium as it's a component of and compared to duty rigs, and ADG isn't on a calendar day but a shifted base time clock.

One other point, I don't believe Southwest's network currently flies any redeyes. The AirTran network does.
