A spokesman for Baltimore-Washington International Thurgood Marshall Airport says the plane landed safely about 10 p.m. Friday. Spokesman Jonathan Dean says airport fire and rescue crews met the plane as a precaution.
Southwest spokesman Paul Flanigan says Flight 3858 was carrying 125 passengers. He says flight attendants reported smoke in the rear cabin.
Flanigan says the plane was taken out of service so mechanics could inspect it, and passengers were being flown to Philadelphia on another aircraft. No one was hurt.
