On my flight the other day, I had two active military men sitting in main cabin. One was in full uniform and the other was wearing a military t-shirt. We got everyone boarded pretty quickly, and we still had four open seats in first class.
One of the men sitting in first class asked us if we could move the two military men from main cabin to first class and he’d pay for their upgrade fee to thank them for their service. I just about died from the sweetness. There are still good people out in the world!
