Today, CommuteAir operates more than 1,600 weekly flights, exclusively on behalf of United Express, serving over 75 U.S. destinations and 3 in Mexico.

In July 2001, the company announced plans to downsize its fleet and workforce by approximately half and change the route structure of the airline.

[5] On October 2, 2008, the company began operations out of Newark Liberty International Airport, following Continental Airlines plan to adjust to the softening industry.

[11] On November 9, 2015, CommuteAir announced that it has reached an agreement with United Airlines to significantly increase the number of airplanes flown under the United Express brand by adding Embraer ERJ 145 jet operations to the company's existing fleet of Bombardier turbo-prop aircraft.

In July 2016, CommuteAir began commercial service with its inaugural flight on the ERJ 145 jet from Washington, D.C. to Columbia, SC.

The latter marks the return of the ERJ 145 to the Denver United Express fleet since COVID and the cessation of operations by Trans States Airlines.

On January 19, 2023, hacker maia arson crimew announced she had compromised web servers belonging to CommuteAir and obtained access to flight and personnel scheduling systems, the personal data of airline staff, and a 2019 copy of the US Government No Fly List.

[citation needed] The CommuteAir fleet was once composed entirely of Beechcraft 1900 aircraft, operated for US Airways Express and later for Continental Connection.

Factors related to the accident were: weather conditions and possible precipitation static interference, caused by inadequate grounding between the radome and fuselage that could have resulted in unreliable glide slope indications.

[28] The National Transportation Safety Board (NTSB) attributed the accident to confirmation bias which prompted the pilots to continue descending even though they could not see the runway due to snow.

Contributing factors were poor decision-making by the captain, fatigue of the first officer, and misalignment of the localizer caused by snow.
