Boeing’s troubled 737 MAX returns to US skies on Wednesday — 20 months after federal officials grounded the jet in the wake of two crashes that claimed 346 lives.

Members of the media will take a chartered American Airlines flight from Dallas to Tulsa — marking the first time anyone besides regulators and industry personnel have flown on the jet since March 2019.

Federal Aviation Administration officials cleared the 737 MAX to resume commercial trips last month, saying Boeing had identified software and training changes required to put the jet back in service.

President Trump grounded the model in March 2019 after a 737 MAX crashed shortly after takeoff in Ethiopia, killing all 157 people on board.

That crash came months after a Lion Air flight crashed under similar circumstances, taking 189 lives.

A congressional investigation released in September called the crashes “the horrific culmination” of “repeated and serious failures” by both Boeing and the FAA.

With the federal green light, airlines across the globe plan to resume commercial flights in the jet this month. American’s first such trip will be a Dec. 29 flight from Miami to New York.

The industry has spent hundreds of billions of dollars on the latest 737 upgrade.

But crash victims families are protesting the return to service, because the final investigation into the Addis Ababa crash has yet to be published. They’ve advised travelers to avoid riding in the model.

“The plane is inherently unstable and it is unairworthy without its software,” Michael Stumo, whose daughter Samaya Rose Stumo died in the 2019 crash, told CNN last month.

“They haven’t fixed it so far. The flying public should avoid the MAX in the future. Change your flight.”
