American retires its last MD-80s in early September

Fort Worth, Dallas - American Airlines will retire its last 26 McDonnell Douglas MD-80 aircraft in early September. The last aircraft will take off from Dallas-Fort Worth on September 4 for its last flight and arrive at Chicago O'Hare the same day.

The carrier's MD-80s are 20.8 years old on average. The retired planes will be ferried to Roswell.

American is planning to replace its MD-80s with Boeing 737 MAXs. The worldwide grounding of the 737 MAX jets caused rumors that the operator would postpone its withdrawal plans for the MD-80s.

The airline said it would alter its schedule if the 737 MAXs are not allowed to return to service until September, but the MD-80s will be removed from the service as it was planned before.

This week, the U.S. Federal Aviation Administration has announced that it detected a new safety risk on the grounded 737 MAX jets. The regulator asks Boeing to address the problem before the aircraft returns to service.

After September 4, Delta Air Lines will be the only US airline to operate the MD-80s. Allegiant Air had retired its last MD-80s last year in autumn.
