My son (21 yrs old) home on military leave took an Allegiant flight to Knoxville, TN with his girlfriend. The trip was from Thursday 730 PM & return was Sunday at noon. He said parking was confusing & they asked a security officer for parking directions. The website said there was parking for $13 day. The officer told him it was $28 a day. He showed the printout that I had given him. Again the officer said $28 a day. The TSA agents were rude as well. When he went to pick up car, he was charged $120 for 2 1/2 days parking. Apparently he had been directed to the hourly lot. According to the website the maximum fee is $28 for 24 hours. How the heck did they come up with $120? He was foolish & paid it. Will never send anyone to that airport again. Shame on Sanford Airport for their shady information.
