Which Narrowbody Aircraft Is Delta Air Lines The Largest & Only US Operator Of?

With around 1,000 mainline aircraft, Delta Air Lines boasts one of the largest fleets in the world and is only rivaled in size by American Airlines and United Airlines. Delta’s fleet is also notable for being comparatively diverse. Even though JetBlue has invested heavily in the A220 and Breeze is transitioning to an all-A220 fleet, Delta is the only North American airline to operate the A220-100.
