The Boeing 757-200 taxied from the parking area to runway 22R at KEWR for eight minutes, covering 2 nm, and departed on a take-off roll of 5,851 ft (61 % of the runway). Rotation occurred at 157 kt. Local weather was 66 °F with a wind of 2 kt from 289°, a 1 kt cross-wind and no head-wind.

Initial climb to 1,000 ft agl took 21 seconds, averaging 2,186 fpm and reaching 167 kt at the top of the climb. The aircraft then climbed from 984 ft asl to 33,509 ft asl in 13 minutes, covering 73 nm, beginning about 1 mile east of Elizabeth. Level flight at 34,000 ft asl continued for 105 minutes, covering 726 nm, starting overhead Palmerton.

A subsequent climb from 33,999 ft asl to 35,998 ft asl took 3 minutes over 21 nm, beginning 3 mi north-west of Riverside. Level flight at 36,000 ft asl lasted 20 minutes, covering 136 nm, starting 2 mi west of North English. The aircraft then climbed from 36,001 ft asl to 37,995 ft asl in 3 minutes over 21 nm, beginning 2 mi east of Walnut. Level flight at 38,000 ft asl continued for 45 minutes, covering 300 nm, starting 2 mi north-west of Neola.

Descent from 38,000 ft asl to 12,002 ft asl took 16 minutes, covering 97 nm, beginning 6 mi south-east of KHEQ Holyoke Airport. Level flight at 12,000 ft asl lasted 27 minutes, covering 121 nm, starting 6 mi south of 6CO5 Montrose BLM Heliport. A further descent from 11,994 ft asl to 11,032 ft asl took 2 minutes over 8 nm, beginning 3 mi north-west of CO80 Fowler Airport. Level flight at 11,000 ft asl continued for 15 minutes, covering 76 nm, starting 3 mi east of Boone. The final descent from 10,987 ft asl to 6,904 ft asl took 4 minutes, covering 17 nm, beginning 3 mi south of 1CO8 Everitt Airport.

On final approach to runway 35L at KDEN, the aircraft descended from 1,557 ft agl to 155 ft agl in 93 seconds. Stabilisation checks at 1,000 ft and 500 ft above the runway were met for gear down, landing flap, sink rate, glideslope, centreline and wings level; the speed check was not met at one gate. Configuration was landing gear down at 3,216 ft agl at 225 kt, and final flap position 5 at 1,420 ft agl at 185 kt.

Landing on runway 35L (length 12,014 ft) occurred with a good threshold height. Threshold speed was slightly below target at 132 kt. The flare was described as perfect; the aircraft floated before touchdown. Touchdown was 1,396 ft beyond the touchdown zone at 120 kt, with a fair rate of -220 fpm and very good alignment. Local weather was 56 °F with a wind of 4 kt from 300°, a 3 kt cross-wind and a 2 kt head-wind. No bounce occurred. Total landing distance was 6,515 ft (54 % of the runway) and rollout alignment was perfect.

After landing, the aircraft taxied to the parking area in five minutes, covering 1 nm. The entire flight covered 1,607 nm in 270 minutes and used 31,280 lb of fuel.
