The flight crew was instructed to hold short of the ramp area due to another airplane occupying the alleyway to their assigned gate. Once the other airplane departed the alleyway flight 1101 could taxi to their gate. The flight crew reported multiple announcements were made reminding passengers to remain seated since they were not at the gate. Believing the cabin was secure, they began to taxi to the gate for parking. Shortly thereafter, they received a call from a FA indicating that there was a line at the aft lavatory and that the cabin was not secure. The captain applied the brakes and inadvertently brought the airplane to an abrupt stop. The flight crew then received a call advising them of multiple FA injuries. At the time of the event, FA-A and FA-D were assisting a passenger who was vomiting profusely. When the aircraft came to an abrupt stop, FA-A sustained an injury to her wrist, while FA-D was thrown to the floor and hit her head. Upon being notified of the injury, the flight crew requested to have emergency medical technicians (EMT) meet the aircraft at the gate. FA-A and FA-D were transported to local hospitals where one was diagnosed with a minor wrist injury and the other a serious head injury. ## Aircraft - Registration: [N633NK](https://openairdocs.org/aircraft/N633NK), registered now, S/N 6345, built 2014 (OpenAirDocs) - Reported make and model: AIRBUS A320-232 - Registry model: [Airbus A320-232](https://openairdocs.org/model/airbus-a320-232) (registry code 3940004) (OpenAirDocs) - Registry engine: [IAE V2527-A5](https://openairdocs.org/engine/iae-v2527-a5) (registry code 34604, turbo-fan) (OpenAirDocs) - Category: Airplane - Serial number: 6345 - Year built: 2014 - Airframe hours: 34631 - Engines: IAE V2527-A5 24800 lbs thrust turbo fan; IAE V2527-A5 24800 lbs thrust turbo fan - Damage: No damage - Flight: Part 121 - Operator: Spirit Airlines Inc. - Registered owner: Bank Of Utah Trustee - Airworthiness certificate: Standard, Transport - Last inspection: Continuous airworthiness, June 9, 2023 - Departed: Charolette, NC - Destination: Same as departure - Flight plan: IFR - Airport: MCO, Orlando Intl, runway 17L, 9,001 × 150 ft, concrete - Equipment: ADS-B, Angle of attack indicator, Stall warning system, Satellite tracking device, Onboard weather, Auto-pilot, Data recorder, Electronic multifunction display, Electronic primary flight display ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
