If you live in base and prefer day trips, you are absolutely correct. He's at NK, like me, and I am a commuter by choice. Bid 4 day trips to minimize time spent commuting. I can hold trips that pay 20hrs and block 12hrs, and trips that pay 21hrs and block 21hrs. So, yeah, spending 18 hours on the beach in SJU is time wasted to you, because your alternative is being at home. But since my trip is 70hrs TAFB either way, I will pick the one with the least work, for a negligible decrease in pay. And I think that that was what he was getting at...
