United Airlines, in the aftermath of the COVID-19 pandemic, has established itself as a leading airline in the United States. The airline operates over 1,000 aircraft within its mainline fleet and maintains a network that spans North America and beyond.
The airline's operations are supported by several strategic hubs located at major airports such as Denver International Airport, Chicago O'Hare International Airport, and Los Angeles International Airport. These hubs facilitate the arrival and departure of nearly all United flights.
United's fleet is diverse but heavily features Boeing aircraft models including the 737-700 through MAX 9 series, the 757-200 and -300, various models of the 767 and 777 series, as well as three versions of the Dreamliner: 787-8, -9, and -10. Alongside these are Airbus aircraft like the A319s and A320s which remain integral to United’s flight schedule despite their age.
