We're really hoping and praying she didn't have a miscarriage," passenger Bethany Bitt told KLAS.Several nurses and a doctor aboard the flight also leaped into action when another passenger was thought to be having a seizure."She was seizing. I started calling out actions, telling people to move—I need this, I need that. And two other nurses came and a doctor came and we got her stable," said passenger and nurse Nyeesha Brown.Medical personnel boarded the plane upon landing in Utah.Passenger Bryan Evans gave his unsettling account from a seat near the wing."I was over the wing. Just watching the wing shake and shutter and feeling the haul," he said. "It was pretty terrifying."@FlyFrontier 1116 should have never taken off. 200+ are lucky to be alive. 50+ wind gusts on takeoff, 2 medical emergencies #flightfromhell— the Dude (@BryEvans) October 9, 2017Frontier Airlines denied reports of turbulence, essentially defending its decision to take off."Flight 1116 operating from Las Vegas to Cleveland last night diverted to Salt Lake City for a passenger medical situation. The plane was on the ground for 90 minutes before departing and continuing on to Cleveland," a spokesperson said. "There were no reports of severe turbulence from the crew, the diversion was for an onboard medical situation.""It was windy in Las Vegas last night which may have made it a little bumpy but it was not a turbulence event."READ MORE: Airline Pilot Collapses Mid-Flight in EuropeHowever, the flight's passengers remain adamant that things were far from normal.Passenger talks about chaos on Frontier Flight 1116. pic.twitter.com/hSAmctElSp— Damon Maloney (@Dmaloneytv) October 9, 2017According to KLAS, about a dozen people got off the flight in Utah. Some requested medical attention while others were simply too rattled to continue.TravelPulse Executive Editor Michael Schottey was on an American Airlines flight inbound to Las Vegas later Sunday night which was diverted to Phoenix because of wind gusts. American pilots in this situation decided the Vegas winds were too powerful and refueled while waiting for the weather to clear. Even with winds dying down to a fraction of what they were earlier, the approach to Vegas was still a choppy and frightening event, according to SchotteyFrontier's decision to operate the flight as scheduled may have been influenced by recent fines levied against the airline. Last month, the U.S. Department of Transportation (DOT) fined the low-cost carrier $1.5 million for violating rules regarding lengthy tarmac delays.Follow @_Pat_Clarke
