United Airlines uses its narrowbody Boeing 737 MAX 8 aircraft for flights throughout North America. Some of United Airlines’ longest flights using its Boeing 737 MAX 8s are flights of more than 3,300 miles between airports on the East Coast and Ted Stevens Anchorage International Airport (ANC) in Alaska. While sitting aboard a narrowbody jet for more than seven hours is uncomfortable, United Airlines also deploys its Boeing MAX 8 aircraft on several routes less than 200 miles.
