A JetBlue flight traveling from California to Florida was diverted to Oklahoma City early morning Wednesday after an unknown odor was reported coming from the cockpit.

The plane landed at the Will Rogers World Airport (WRWA) at 2 a.m. local time (3 a.m. EDT), CBS News reported. Oklahoma City Fire Department attended to five of the 135 passengers for breathing problems due to the odor, the source of which is yet to be identified.

Eight ambulances were also summoned to the scene, and many of the passengers used oxygen tanks to stabilize their breathing. Even though the WRWA fire department sent back the city fire department units, some fire fighters stayed back to help out the passengers.

This is not the first instance of passengers inside a plane falling sick due to an unknown odor on the flight. American Airlines in particular have come under fire for making headlines due to all the wrong reasons.

An American Airlines flight, scheduled to leave from Los Angeles International Airport to Washington Dulles International Airport in Washington, D.C., was reportedly delayed for more than four hours July 9, 2017, after a strong smell of urine wafted in from the cabin.

Leslie Scott, an American Airlines spokeswoman, told Fox News: “Flight 2645 from LAX to Dulles was delayed due to a cabin cleanliness issue. We brought in a new aircraft and the flight has since departed approximately 4.5 hours late. We apologize to our customers for the inconvenience,” Scott said.

Dana Milbank, a columnist for the Washington Post, tweeted that everyone was given complimentary pound cakes as a means of consolation for the delay.

On July 16, passengers on an American Airlines flight were forced to evacuate after one of them “passed gas” on the plane, Fox News reported. However, Andrew Sawyer, a spokesperson for Raleigh-Durham International Airport, where the plane landed, denied the incident and said the passengers disembarked the flight normally after it landed.

“Medical call for persons affected by an odor came in after plane deplaned normally,” Sawyer told Fox News. Nevertheless, the incident did not stop Twitter users from posting hilarious reactions on the social media platform.

The airlines was plagued by a similar problem July 25 when three people had to be rushed to the hospital after they complained of smelling an unknown odor just before their flight landed at the Miami International Airport (MIA).

A representative of the airlines told Fox News: “Prior to landing at Miami International Airport (MIA), three crew members reported a possible odor in the cabin of American Airline flight 1625.”

The flight was carrying 98 passengers and five crew members at the time. One passenger had to be checked out by medical personnel at the airport itself, while three of the crew members were admitted to a local hospital for evaluation.
