Thirteen teenagers and three chaperones returning home to the Boston area this morning from a group trip to Ecuador were stricken with stomach and intestinal maladies aboard an American Airlines flight from Miami, authorities said.

The group had connected with AA Flight 1201 in Miami after their journey originated in Quito, Ecuador.

“A group of 16 children and chaperones, part of a group of around 40, felt ill on a flight to Boston. No other passengers reported feeling ill. American requested paramedics to meet the aircraft upon arrival at Boston Logan,” American Airlines said in a statement.

Samantha Decker, a spokeswoman for the Massachusetts Port Authority, said the afflicted were taken to Massachusetts General Hospital to be evaluated, but their complaints were believed to be minor.

Scanner chatter on state police and Boston EMS channels reported they were suffering from stomach and intestinal upset.

The Boeing 737-800 landed at Logan shortly after 9:30 a.m.
