JACKSONVILLE, Fla. -- An Allegiant Air flight had to make an emergency landing at Jacksonville International Airport Wednesday morning due to pressurization problems, officials said.

Allegiant flight 758 was diverted to Jacksonville after reporting a "pressurization issue," JIA spokesperson Debbie Jones confirmed to First Coast News. The aircraft landed safely at 8:13 a.m., Allegiant Air said, then parked at Gate C3.

The flight departed Orlando Sanford International Airport just after 7:30 a.m. and was en route to Indianapolis International Airport, Jones said.

There were 155 passengers and six crew members onboard, an Allegiant Air spokesperson told First Coast News.

"A replacement aircraft will be sent to JAX from SFB and is scheduled to depart JAX at 12:40 p.m. and arrive in IND at 2:40 p.m. Passengers will be receiving a refund for the flight segment, food at the gate, the option to change their flight to another one in the Allegiant network and $200 vouchers for future travel on Allegiant," the airline said in a statement.

The aircraft was taken out of service and will be inspected to determine the exact issue, according to Allegiant.
