Boeing 737 MAX 8: How to find out if you’re booked on troubled plane

After the crash of a Boeing 737 MAX 8 in Ethiopia this past weekend, several international air carriers have grounded the planes over safety concerns.

An investigation is underway into the Sunday morning crash of an Ethiopian Airlines flight that slammed into the ground shortly after takeoff from Addis Ababa, killing all 157 people on board. The plane was headed to Nairobi, Kenya.

The Ethiopian Airlines crash is the second crash of a 737 MAX 8 in six months. A Lion Air Boeing 737 MAX 8 crashed in the Java Sea on Oct. 29, killing everyone aboard.

David Soucie, an aviation analyst for CNN, said in an interview Monday morning that he would recommend the planes be grounded because of the similarities between the Ethiopian Airlines and Lion Airlines crashes.

Soucie, who has worked with the Federal Aviation Administration as a member of the Safety Management Implementation (SMI) Committee, said he had never before suggested consumers be wary of a particular type of airplane, but that he was suggesting that after reviewing the flight data from both crashes.

"I've never, ever done this before," Soucie said on CNN's "Newsroom.” "I've never said that, 'Hey, it's unsafe to fly a particular model' but in this case, I'm going to have to go there. I just looked at the flight data of that aircraft: It’s strikingly similar, same issues we had with the Max Air. So yeah, I would watch for that airplane."

Also on Monday morning, Ricard Quest, aviation analyst for CNN, said he would suggest that “we proceeded with an abundance of caution” when it comes to using the plane.

“The Chinese have said we are not sure” the 737s are safe to fly at the moment, while “the Americans and Europeans are saying we are looking at it.”

A handful of airlines have grounded the 737 MAX 8 including Cayman Airlines, Ethiopian Airlines, Aeromexico, Aerolíneas Argentinas, Comair Airways, Norwegian Air and Eastar Jet.
