Portland, Ore.-based FlightStats earlier this month released its annual report on airport performance for 2007, confirming a considerable decline in on-time flight arrivals compared to the previous year. On-time arrivals at the 28 largest domestic airports dropped by nearly 5 percentage points to 71.65 percent in 2007 compared to the previous year, according to a company release. In addition, 11.2 percent of all flights were delayed on arrival by more than 45 minutes, meaning "scores of travelers" likely missed connections as carriers schedule connection more tightly and have fewer re-accommodation options due to fuller flights. The best on-time arrival performance for 2007 was at Orlando International Airport 's with 78.49 percent of flights arriving on time. The worst airport for delays was John F. Kennedy International Airport with just 59.78 percent of flights arriving on time. The other two New York metro airports, Newark Liberty International and LaGuardia International, were ranked as the second and third worst airports for delays. Nearly all airports in the report, 26 of the 28 airports, reported lower on-time performance in 2007 from 2006 with an average decline in on-time arrivals of 4.69 percentage points. Only Atlanta's Hartsfield Airport and Seattle-Tacoma International saw an improvement. The excessively delayed flights (more than 45 minutes late on arrival) that can create as much inconvenience for travelers as a cancellation in a tightly scheduled system increased at a number of airports, according to FlightStats. Of all the airports in the report, Atlanta and Philadelphia were the only ones with a slightly reduced factors of excessive delay with drops of 2.3 and .63 percentage points, respectively. Every other airport had higher factors of excessive delays.
