Hawaii Study: Domestic flights down 24% at Honolulu Airport since 2007 By Shane Nelson / May 12, 2013 Share 1 -- Honolulu Airport has seen domestic flight departures plunge 24% over a nearly six-year period ending in October 2012, according to a study released May 8 by researchers at the Massachusetts Institute of Technology (MIT). The total number of available air seats on domestic flights departing from the airport has also dropped significantly since 2007, sinking 19.6%, to 8.4 million seats, the study found. Researchers at the Massachusetts Institute of Technology (MIT) said that U.S. airlines cut the number of scheduled domestic flights by 14.3% nationwide from 2007 through the fall of last year, attributing the cutbacks to restructuring in the industry and the use of larger aircraft. Honolulu certainly wasn’t the only Aloha State airport suffering significant domestic flight reductions over the last six years. Domestic service departing from the Hilo Airport on the Big Island of Hawaii dropped 37.4% while those flights leaving Lihue Airport on Kauai sank 12.7%, according to the MIT study.
