On Wednesday, President Donald Trump announced a grounding of Boeing 737 Max 8 and Max 9 planes after an Ethiopian Airlines crash last weekend.

The crash killed all 157 people on board. It also came after another 737 Max 8 crashed last October, killing 189. China, Australia, the United Kingdom, the Republic of Indonesia and Singapore have also temporarily grounded the 737 Max line.

CNBC reported there are 370 Boeing 737 Max 8 and 9 planes in use around the world. In the United States, the planes were flown by 74 airlines.

As of Wednesday afternoon, no airline anywhere in the world is using the affected models. USA Today reported the U.S. government's decision has grounded the last of them.

The AJC reported Southwest had been operating 34 737 Max 8s, including some flights from Atlanta.

American Airlines used the Max 8 as well, though none of its Max 8s are used on flights to or from Atlanta. United Airlines operated the Max 9.

On Tuesday,  the FAA chief said a review of 737 data "(showed) no systematic performance issues and (provided) no basis to order grounding aircraft."

In the FAA announcement, the agency cited "new information" from its investigation of the Ethiopian crash that indicated similarities between it and the crash last October.

The agency said these findings “warrant further investigation of the possibility of a shared cause for the two incidents that needs to be better understood and addressed.”
