JetBlue is adding new service out of Bradley International Airport near Hartford, Conn., later this year. The carrier will begin nonstop service between Bradley and Cancún, Mexico, on Nov. 19, followed by service to Los Angeles, Las Vegas and San Francisco on Dec. 18, which JetBlue said will give it the largest number of destinations of any carrier operating out of Bradley. Connecticut last week eased its travel restrictions, enabling arriving passengers to avoid 14-day quarantine requirements by providing a negative Covid-19 test result either upon arrival or within 72 hours prior to arrival.
