CNN  — 

An investigation is underway after a Boeing 737 Max 8 aircraft crashed Sunday in Ethiopia, killing all 157 people on board.

It is the second time in less than six months that one of the planes has crashed within minutes of takeoff, after a new Lion Air Boeing 737 Max 8 flight went down over the Java Sea last October, killing 189 people.

Both crashes are under investigation and there is no evidence of a link between the two, but similarities between the incidents have prompted caution among some aviation authorities and airlines.

There are approximately 350 Boeing 737 Max 8 aircraft in operation worldwide, being flown by 54 operators, according to the US Federal Aviation Administration (FAA).

Travelers can check the full list of airlines that fly the plane on the Boeing website.

Read on to find out which airlines and aviation authorities have grounded Boeing 737 Max 8 aircraft, and which will continue to fly the planes.

Who is grounding planes?

Ethiopian Airlines

The carrier has grounded the remaining four Boeing 737 Max 8s in its fleet until further notice, as an “extra safety precaution.”


Chinese airlines including the “Big Three” Chinese carriers – Air China, China Eastern and China Southern – operate 97 of the planes, according to state-run media. In the wake of Sunday’s crash, the country’s Civil Aviation Administration ordered all domestic 737 Max 8 jets out of the air by 6 p.m. local time Monday, citing “zero tolerance for safety hazards.”


Indonesia temporarily grounded all Boeing 737 Max 8 planes operated by its airlines on Monday, pending further inspections.

In a statement, the Directorate General of Air Transportation at the Ministry of Transportation said the policy would “ensure that aircraft operating in Indonesia are in an airworthy condition.”


The Mexican carrier is temporarily suspending the use of its six 737 Max 8 planes “until more thorough information on the investigation of flight ET302 accident can be provided.”

Aerolíneas Argentinas

The Argentine airline said it would temporarily suspend commercial operations for the five 737 Max 8s in its fleet.

Cayman Airways

Cayman Airways operates two new Boeing 737 Max 8 aircraft. It said Monday it was grounding both planes “until more information is received.”

Comair Airways

The South African carrier said it would remove the 737 Max 8 from its flight schedule, despite the fact that “neither regulatory authorities nor the manufacturer has required it to do so.”

“While Comair has done extensive preparatory work prior to the introduction of the first 737 Max 8 into its fleet and remains confident in the inherent safety of the aircraft, it has decided temporarily not to schedule the aircraft while it consults with other operators, Boeing and technical experts,” the airline said in a statement.

Eastar Jet

South Korean low-cost carrier Eastar Jet said it would temporarily ground its two 737 Max 8 planes starting Wednesday to “dispel the worry and concern of the people.”

The company said operations would resume when there were no more safety concerns.


TUI Airways – one of the UK’s largest air carriers – issued a statement Tuesday confirming that all 15 of its 737 Max 8 aircraft operating in the UK have been grounded.

That decision follows guidance from the UK
