Delta Air Lines announced that they will accelerate the retirement of their MD-88 and MD-90 airliners after the coronavirus decimated the airline industry, and Lufthansa announced that the Airbus A340, A380, and Boeing 747 won’t be returning either. Now, adding to the list, American Airlines has announced that they will be putting the A330, Boeing 757-2o0, 767-300ER, Embraer E190, and Bombardier CRJ200 out to pasture. So it looks like once commercial aviation limps back into business (hopefully) in the coming months, the skies will be a much less interesting place.
