Bradley International Airport saw a 4.5-percent decline in the number of passengers boarding its commercial flights in 2012, according to preliminary data from the Federal Aviation Administration.
Connecticut’s biggest airport sent 2.64 million passengers into the skies last year, compared to 2.77 million in 2011, the FAA said.
Bradley’s enplanements peaked in 2005 at 7.2 million before falling through 2009. Numbers had increased in 2010 and 2011 thanks to the addition of JetBlue Airlines and Frontier Airlines and several non-stop routes. Frontier has since left Bradley.
Boston’s Logan International Airport saw an increase of eight-tenths of a percentage point in 2012 while T.F. Green in Warwick, R.I. saw its enplanements decline 5.8 percent. Across the country, enplanements were up 0.86 percent.
The FAA will release final 2012 enplanement data in September.
