American returned its last Boeing 737-800 grounded as a result of the COVID-19 pandemic to revenue service last week. Registered as N920AN, the nearly 25-year-old aircraft had been in storage for more than four years.
In 2020, the Fort Worth-based airline placed over 70 so-called ‘Block 1’ 737-800 aircraft – those delivered from 1999 to 2001 – into long-term storage programs. American gradually returned these aircraft to revenue service as demand for air travel increased during the pandemic.
According to Cirium Fleet Analyzer data, N920AN was the last remaining 737-800 in a long-term storage program within American’s fleet. In November 2023, it ferried from the carrier’s storage facility in Roswell, N.M. to Jacksonville, Fla.’s Cecil Airport, presumably for interior retrofits and return to service checks.

As first pointed out by aviation watchdog JonNYC on Twitter/X, the 737 re-entered revenue service on April 8, 2024. American has over 300 Boeing 737-800 in addition to nearly 60 737 MAX jets.
Due to the COVID-19 pandemic, American retired a handful of fleet types in 2020, including the Embraer E190, Airbus A330, Boeing 757, and Boeing 767. The airline also placed several aircraft into storage programs as worldwide travel demand slumped.
