Three Easyjet cabin crew members "hit the ceiling" when a flight en route from Gatwick to Naples hit severe turbulence.
One of the flight attendants even fractured a hip, while one was reportedly knocked unconscious during the incident.
The captain was then forced to divert the plane, carrying 154 passengers, to Rome.
Newlyweds Lucy and David Westbrooke, from Tunbridge Wells, were en route to their honeymoon when the plane hit a violent thunderstorm.
Speaking to the Evening Standard, Mrs Westbrooke said: "We nose-dived. All three cabin crew hit the ceiling.
"It was terrifying - what a start to married life. One stewardess said this was by far the worst she had experienced."
According to the Daily Mail, she added: "Suitcases were being thrown out of the lockers overhead. There was just utter panic. People were screaming. There was a baby thrown up in the air and the mother was just beside herself."
Mr Westbrooke told the paper: "It was the worst air turbulence I've ever felt. You could just feel the plane nosedive. The air stewards and stewardesses were telling people to put on their seatbelts.
"All three of them went up to the ceiling, and damaged the ceiling. All three knocked the panels out, and one stewardess was knocked out. There were a few nurses on doctors on board.
"The main focus was on the stewardess. They were going round making round everyone was okay. Lots of people were being sick. They ran out of sick bags."
After landing in Rome, passengers continued their journey by bus to Naples, and Mr and Mrs Westbrooke finally made it to their honeymoon destination of Capri at 7pm on Monday - eight hours late.
According to the Independent, an Easyjet spokesman said: "Unfortunately due to the turbulence, one of our crew sustained an injury, and as such were met by paramedics upon arrival at Rome Fiumicino airport in line with our procedures.
"The aircraft landed safely and routinely and all passengers disembarked normally and were transported to Naples by coach. EasyJet would like to apologise to passengers for any inconvenience caused."
