Behind me in line, a young mother was trying to soothe a crying toddler while holding an infant carrier in her left arm.

Next to her stood a young Army specialist hauling two heavy canvas duffels, looking completely drained after what had obviously been a long overseas trip.

“I’d like to trade away my upgraded seat,” I said, keeping my voice measured and exact.

“Give the first-class row to that family so they can sit together on the flight.”

The agent glanced past my shoulder at the young family, then looked back down at her keyboard.

“The main cabin is totally full, ma’am,” she said, her fingers hovering over the keys.
