LEE COUNTY, Fla.-- Security lines around lunch time were moving up to speed at Southwest Florida International Airport Wednesday.

RSW does not use the controversial full body scanners, but instead relies on metal detectors to screen passengers.

However, TSA agents are authoritized to perform enhanced pat downs on those travelers who set off the alarm.

The stepped-up security measures did not appear to be causing delays Wednesday.

Lines at one airline's check-in counter were moving a bit slower than expected.

Spirit Airlines was checking in passengers without computers after experiencing problems with its computer system.

The South Florida-based airline has been upgrading its systems and its website was also down early Wednesday morning.

An airline spokeswoman says "all flights are operating and we have not had any cancellations."
