A San Diego flight bound for Tulsa was diverted to Phoenix due to what was described by passengers as an “odor that came through the plane and was then gone,” Phoenix Fire said.
Frontier Flight 1764 left San Diego at 6:50 a.m. Sunday and landed in Phoenix around 11:25 a.m. local time.
The plane landed safely, and the passengers were able to deplane in Phoenix. Seventeen passengers requested to be evaluated by Phoenix Fire, and a 62-year-old man was taken to the hospital as a precaution.
The cause of the odor will be investigated by Frontier, Phoenix Fire said.
Frontier told NBC 7 in a statement:
“Frontier Airlines flight  from San Diego to Tulsa landed in Phoenix this morning after an odor was detected by a member of our crew. Safety is the priority at Frontier and the decision to land in Phoenix was made out of an abundance of caution. As is standard procedure, anyone requesting a medical evaluation receives one. Arrangements are being made to allow passengers to continue to their destinations.”
This is the second time in a week a Frontier flight on the San Diego-Tulsa route has been diverted because of an in-cabin odor.
On May 20, Flight 1839 from Tulsa to San Diego had to be diverted to Albuquerque because of a chemical smell.
