A Texas woman is suing Continental Airlines and three other carriers over mental trauma she says was caused by a turbulent flight, the Houston Chronicle reported.

Colleen O'Neal alleges that the October 2009 flight from College Station, Texas, to Houston -- a usually short flight that ended up taking more than two hours -- encountered extreme turbulence that caused her to fear for her life.

O'Neal experienced post-traumatic stress disorder and now fears flying, which has had a detrimental impact on her career, according to the suit filed Tuesday in Harris County district court.

Also named in the suit are regional carrier Pinnacle Airlines, which operated the flight; Pinnacle's owner, Colgan Air; and United Airlines, which recently merged with Continental.

Spokespeople for United and Pinnacle declined to comment.
