Fly from Sydney to Hong Kong on a Qantas Airbus A380 and you'll find the 180-degree fully flat beds, but a Qantas Boeing 747 on the same route has angled lie-flat beds.

On the 777-300, used on Flight 137 from DFW to Hong Kong, the business-class seats stretch out into flat beds 6-feet, 4-inches long, while first-class seats recline flat with an additional four inches. First-class passengers also receive a turndown service and pajamas to keep for the long flights.n the 777-300, used on Flight 137 from DFW to Hong Kong, the business-class seats stretch out into flat beds 6-feet, 4-inches long, while first-class seats recline flat with an additional four inches.
