Air Canada A220 Returns to Denver Due to Odor on Toronto Flight

TORONTO- An Air Canada (AC) flight en route to Toronto Pearson International Airport (YYZ) had to return to Denver International Airport (DEN) due to a peculiar odor reported on board.

Flight AC 1038, which was operated by an Airbus A220, successfully returned to Denver where all 117 passengers and 5 crew members were safely evacuated for precautionary reasons.

Odor Issue on the Flight

The “acrid” odor was first picked up in the galley area just after takeoff. Emergency slides were deployed, enabling quick evacuation of passengers, as reported by FOX31.

While evacuating, one passenger experienced a minor injury. After deboarding, passengers were provided transportation back to the terminal, and Air Canada arranged alternative travel options.

Despite the disruption, Air Canada noted that all safety protocols were strictly followed, with the flight crew managing the situation effectively throughout.

Evacuations like this, although rare, usually occur only when there is a potential threat to passenger safety.

The crew’s swift actions helped to mitigate risks, ensuring a smooth evacuation process.

Aviation bodies stress that precautionary measures, such as these, play a vital role in upholding high safety standards in commercial aviation.

Recollections of a Similar Incident

Another occurrence involved a Hawaiian Airlines (HA) Airbus A330-200, which faced a similar situation on June 23, 2025. The flight, HA864, was heading from Tokyo Haneda Airport (HND) to Honolulu (HNL).

Shortly after takeoff, the crew recorded an unusual smell in the cockpit and opted to return to Haneda. The plane, carrying 268 passengers and 13 crew members, landed safely after 35 minutes.

Japanese authorities noted there was no visible smoke or fire. The aircraft was able to taxi back to the apron without any external help.

Subsequently, the aircraft remained grounded for approximately 26 hours for maintenance to investigate the source of the odor. Although the cause is still unknown, the crew’s prompt actions ensured that safety was never in jeopardy.

Commitment to Passenger Safety

Both Air Canada (AC) and Hawaiian Airlines (HA) have reiterated their dedication to the safety of passengers and crew.

Although incidents involving odors are uncommon, airlines take them seriously and conduct thorough inspections before returning aircraft to service.

Such situations underline the importance of well-trained crews, rigorous regulations, and established emergency protocols that bolster safe air travel globally.
