After a six-hour flight from Massachusetts to Florida in a paratroop-rigged C-47 (military version of DC-3), "seats" were rows of webbing along the sides, and nothing blocking the open door but a few strips of webbing whose strength nobody wanted to test, I'll take a jet with real seats, pressurization, lavatories, food/beverage service and 500-mph ground speed any day. The seat matters to me. The food/beverage service matters to me. How many aisles? Meh.
