Three Delta Air Lines flight attendants were injured after a flight from Quito, Ecuador, to Atlanta experienced turbulence, the airline company said.

After departing Mariscal Sucre Quito International Airport at 11:15 p.m. on Sept. 14, Delta flight 632 was headed to Hartsfield-Jackson Atlanta International Airport for a scheduled arrival of 5:20 a.m. on Sept. 15, according to FlightAware. During the journey, the Boeing 767, which carried seven crew members and 206 passengers, encountered "moderate turbulence," a Delta spokesperson told USA TODAY in a statement.

"Three flight attendants reported minor injuries but were able to continue performing their duties throughout the remainder of the flight," the airline continued.

After landing safely in Atlanta, the aircraft was met by medical personnel who evaluated the flight attendants. There were no passenger injuries reported.

Is turbulence getting worse?

Experts have told USA TODAY that turbulence is growing in both frequency and severity.

Severe clear air turbulence – which is harder to predict and therefore avoid – is 41% more common today than in 1979, according to Paul Williams, a professor of atmospheric science at the University of Reading in the U.K. who studies turbulence.

This past summer, another Delta flight from Salt Lake City to Amsterdam diverted to Minneapolis-St. Paul International Airport after severe weather caused "significant turbulence." 25 people were sent to the hospital, with two crew members sustaining serious injuries.

One passenger told ABC News that several travelers who weren't wearing their seatbelts hit the ceiling from the incident.
