Ian Gregor, an FAA spokesman, said the Boeing 737 reported equipment issues after leaving LAX en route to Boston's Logan International Airport.
It appears a cargo indicator light was faulty, airline spokesman Kent Powell said. The plane was taxied to the gate.
Flight 202 was carrying 146 passengers and six crew members when it departed LAX at 1:10 p.m. and it landed just after 2 p.m.
No one onboard the plane was hurt.
The passengers and crews members boarded another plane and continued to Boston.
