Who flies the Boeing 777-300ER

Two questions in one table. Airframes is what each carrier reported owning in its US DOT fleet filing; seats flown is how much of the type it actually operated. They can rank differently, and the gap is the interesting part.

Operator
United AirlinesUA223.5M16.5%8.8 yr
American AirlinesAA202.8M13.1%12.7 yr
Kalitta AirKAQ7——1.0 yr

Airframes are the latest Form 41 filing; seats flown and share are US DOT T-100 for the type's most-flown operators — a dash means a carrier isn't among them (a freighter operator, or one that flies fewer).

How old is the US Boeing 777-300ER fleet?
