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 AirlinesUA | 22 | 3.5M | 16.0% | 8.7 yr |
| American AirlinesAA | 20 | 2.9M | 13.2% | 12.5 yr |
| Kalitta AirKAQ | 7 | — | — | 0.8 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?
Age is measured from each airframe's delivery date — the FAA airworthiness date where available, otherwise the manufacturer's. Bars share a fixed scale across every fleet page, so two carriers can be compared directly.
