Allegiant Airlines flights in and out of Sanford all appear to be on time as of early Thursday. 

All departures and arrivals Orlando-Sanford International Airport are being reported as on time. 

Multiple Allegiant flights were canceled due to weather Wednesday. 

Hilarie Grey, a spokeswoman for Allegiant, said in an email statement that "an unanticipated change in weather" at about 9 p.m. Tuesday brought low visibility and caused 10 flights bound for Sanford to be diverted to other airports.

Twelve flights in and out of Orlando-Sanford were canceled Wednesday as the airline "works to return to normal operation in the area." That includes moving aircraft and crews that were out of position as a result of Tuesday's weather, Grey said.

Flights to Grand Rapids, Michigan; Youngstown, Ohio; and Allentown, Pennsylvania were among those canceled. 

"Passengers scheduled for travel on the affected flights will receive an automatic refund for the unflown segment of their itinerary," Grey said. "We sincerely apologize to our customers for the disruption to their plans, but the weather situation was unexpected and its impact on our operations in the area severe."
