Thus far 102 737-MAX (out of a reported 350 delivered) are currently grounded by regulators or voluntarily.
96 in China (list from @
juliuswong on airliners.net), 4 in Ethiopia, and 2 in Grand Cayman.
100% of the 737maxes in each of the following fleets:
Ethiopian - 4
Grand Cayman - 2
Joy Air- 1
Air China- 15
Fuzhou Airlines- 2
China Southern- 24
China Eastern- 3
Kunming- 2
Lucky Air- 3
Hainan Airlines- 11
Okay Airways- 2
Shandong Airlines- 7
Shanghai Airlines- 11
Shenzhen Airlines- 5
Xiamen Airlines- 10
Air Canada is not on the list yet, but you won't find me on one. While airline travel is low risk, I'll take an old 767 or Airbus over a 737 max.. On airliners.net someone calculated that the 737NG has 2000x less fatalities per thousand takeoffs than the 737MAX.
