JetBlue says one of its flights returned to Kennedy International Airport because of an unusual odor in the cabin -- the second such incident in a week.

JetBlue Airways Corp. spokeswoman Alison Eshelman said Flight 68 bound for Syracuse, N.Y., left the airport at 9:50 a.m. Tuesday and returned about 20 minutes later. The Embraer 190 was carrying about 59 passengers. There were no injuries and passengers were put on other flights.

A maintenance crew was examining the plane.

Another JetBlue flight, also an Embraer 190, returned to JFK last Tuesday after the pilot reported smelling smoke in the cockpit.

JetBlue shares jumped with other airline stocks Tuesday as oil prices sank. In midday trading, JetBlue rose 46 cents, or 7.6 percent, to $6.53.
