HARLINGEN — Flights were delayed yesterday first due to a national computer snafu and then locally due to weather.
Early yesterday morning, the Federal Aviation Administration said several airlines had problems with a program called Aerodata, which is used to plan weight and balance for flights.
The FAA said the issue was resolved within a couple hours, although American Airlines, United Airlines, Southwest Airlines and Delta Air Lines all reported delays that continued throughout the day.
Around noon, fog in the Lower Rio Grande Valley became a problem, causing delays at Valley International Airport and Brownsville South Padre Island International Airport.
Officials at Valley International yesterday afternoon said several flights were delayed by around 30 minutes due to weather issues and one United Airlines flight from Houston was diverted to Corpus Christi.
In Brownsville, some flights were delayed by up to three hours yesterday afternoon due to fog.
At McAllen International Airport, officials said no delays or weather problems were reported.
By late afternoon, 4,577 U.S. domestic flights had been delayed, and 677 flights canceled. Of those, 1,080 were Southwest flights.
Of those cancellations, 31 were to or from Houston Hobby airport, with another three outbound from Houston International, according to tracking service FlightAware.
In all, both Houston airports saw nearly 200 flights delayed by late afternoon.
The FAA advised travelers to contact airlines directly for flight information and updates.
Airlines said travelers should check online for the latest updates on flights on websites like .
