KANSAS CITY, Mo. (AP) — Officials at Kansas City International Airport say they’ve heard the complaints from travelers about spotty Wi-Fi service and they’re working to make it better.

The Kansas City Star reports the city’s Aviation Department plans to spend $250,000 to completely upgrade Wi-Fi service and make other technological improvements.

The airport started offering Wi-Fi about a decade ago. Overland Park-based Sprint Co. agreed to pay for and install the necessary infrastructure. Customers paid $9.99 for up to eight hours.

When the agreement with Sprint expired, the Aviation Department took over the service and made it free.

Officials say that there have been upgrades since, but not enough to keep up with demand, which has increased dramatically as more people travel with computers and phones they want to use to access the Internet.
