On Sunday, “60 Minutes” aired a scathing segment on the low-cost carrier Allegiant Air. The airline flies out of the Plattsburgh and Stewart International Airports. Allegiant has been flying out of the Plattsburgh International Airport for 11 years. With the expose on the national news magazine, you might think local officials would be worried about one of the major carriers. But those overseeing operations there say while they were taken aback by the report, it doesn’t reflect what officials and passengers in Plattsburgh have experienced.
