Copa Airlines said in a statement that emergency exits over wings are meant to be opened by passengers at lower altitudes to allow evacuations in emergencies. In his statement, Yakel mentioned that no other flights or runaways had been affected and the boy was not injured too.
Customs and Border Protection is investigating the incident.
"And then this guy, I see him jump on the wing and then he starts climbing down the wing and then he just runs", said said Andrea Sepulveda Guzman to CBS San Francisco.
People sitting near the exit row stood up when the boy jumped out and started to shout, others said.
"It was as if he was like flying out, like it was really fast", Sophia Gibson, a passenger who lives in San Jose, told local NBC affiliate KNTV. The passenger has been taken into custody by law enforcement.
The airline said it was cooperating with authorities in the investigation.
It is unknown why the teen jumped out of the plane. Passengers said there was a big commotion when they noticed one of the exit doors was wide open.
Passengers said the teen seemed fidgety and anxious throughout the flight that he acted so quickly, no one had a chance to stop him. The crew detained him until the police arrived.
In 2014, a passenger on a China Eastern Airlines plane said he wanted to "get off the plane quicker" and deployed the emergency slide after the plane landed at Sanya Phoenix International Airport.
