Air Canada flight AC143, an Airbus A321 registered C-FGKN, departed Toronto's Lester B. Pearson International Airport (CYYZ) at 8:12 a.m. local time (12:12 UTC) on August 25, 2026, bound for Calgary International Airport (CYYC). The aircraft lifted off heading west at roughly 259 degrees before curving southwest on climb-out.

SkyMeter's analysis of ADS-B tracking data shows the flight climbed steadily through the 20,000s, then leveled near 29,000 feet for roughly 55 minutes before stepping up again around the 90-minute mark, ultimately reaching a peak of 35,406 feet. Cruise ground speeds held in the 400 to 435 knot range across the prairies, with the heading gradually shifting from about 300 degrees to 278 degrees as the track arced toward Alberta.

Descent began near 9:49 a.m. local Calgary time, with the aircraft dropping from cruise altitude at rates reaching 3,390 feet per minute through the initial descent phase. The approach stabilized on a southerly heading of roughly 180 degrees, and the aircraft touched down at Calgary, completing the roughly four-hour flight by 10:15 a.m. local time.
