Sleek and powerful, Constellations set a number of records. On April 17, 1944, the second production L049, piloted by Howard Hughes and TWA president Jack Frye, flew from Burbank, California to Washington, D.C. in 6 hours and 58 minutes (c. 2,300 mi/3,701 km at an average 330.9 mph/532.5 km/h). On the return trip, the aircraft stopped at Wright Field to give Orville Wright his last flight, more than 40 years after his historic first flight. He commented that the Constellation’s wingspan was longer than the distance of his first flight.

On September 29, 1957, an L-1649A Starliner flew from Los Angeles to London in 18 hours and 32 minutes (about 5,420 mi/8,723 km at 292.4 mph/470.6 km/h). The L-1649A holds the record for the longest-duration, non-stop passenger flight, during TWA’s inaugural London-to-San Francisco flight on October 1–2, 1957, the aircraft stayed aloft for 23 hours and 19 minutes (about 5,350 mi/8,610 km at 229.4 mph/369.2 km/h).
