Major storms and a failed reservation system earlier this year caused on-time flight arrivals to drop significantly at Charlotte-Douglas International Airport.
Federal statistics and airline data show Charlotte-Douglas ranked 27th out of 32 major airports for on-time arrivals during the first four months of the year.
In 2004, 83 percent of flights to Charlotte arrived on time, the nation's second-best rate. This year, it's 66 percent.
That's barely above notoriously slow O'-Hare International in Chicago and the three major airports serving New York City.
Aviation consultant Mike Boyd says Charlotte's ranking was directly related to this year's weather delays and the U-S Airways reservations glitch.
He says the ranking likely would be different if it was done another year.
