Few flights will test an airline’s premium product offerings like a transcontinental service. Passengers are in the air long enough to the point that seat width, cushion support, privacy, power ports, and whether the cabin actually lets one rest. At the same time, passengers are not in the air so long that they will tolerate a modest domestic recliner sold at a premium upcharge. This is why the best transcontinental seats have begun to resemble mini international business-class cabins. These seats feature lie-flat beds, direct aisle access, improved bedding, quieter cabins, and service that treats the route like a flagship service.
