Who Is The Largest by Fleet Size?: It’s Delta!
Delta Air Lines wins this competition compared to American, United & Southwest, having a total of 967 aircraft recorded at the time of writing.
Between the four carriers themselves, they have a grand total of 3,663 aircraft in their fleets, which is quite a staggering statistic in itself.
As orders are fulfilled and more aircraft are delivered, then we will no doubt see these numbers slowly rise in the years to come.
That being said, depending on the strategy of each carrier, the numbers could remain similar, especially if significant fleet renewal is taking place.
But for now, Delta remains the largest carrier by fleet size.
