A flight from Boston to Baltimore made an emergency landing in Philadelphia on Sunday after smoke was smelled on the plane, officials said. JetBlue Airways flight 827 landed safely shortly before 6 p.m. at Philadelphia International Airport, said Victoria Lupica, a spokeswoman for the airport. No injuries were reported. The 95 passengers and four crewmembers were safely evacuated, said JetBlue spokeswoman Victoria Lucia. The flight left Logan International Airport at about 4:40 p.m. The captain chose to land in Philadelphia out of “an abundance of caution” after the crew reported “an odor of smoke” in the cabin, she said. Lupica said mechanics were evaluating the plane, but had not yet confirmed whether there was smoke or what may have caused it. Operations at the Philadelphia airport were not affected, she said. Passengers were scheduled to take a later JetBlue flight from Philadelphia to Baltimore-Washington International Airport, Lucia said.
