The smell was reported by passengers on American Airlines flight 2055 to Los Angeles before boarding, American Airlines officials said.

The troubling smell was possibly from jet fuel, according to WBTV.

Six people had minor injuries and one person had serious symptoms, local outlets reported.

Some victims were treated at a local hospital, and others on-site, WCNC said.

The employees have since been released from the hospital, NBC News said, citing the airline.

American Airlines took the plane out of service for inspection, according to the airline. Charlotte is American’s east coast hub.

The flight cancellation occurred while the airline was experiencing technology issues — contributing to additional delays at the airport on Friday, WCNC reported.

Roughly 731 flights were delayed and 132 were canceled at the airport that evening, the outlet said.
