Who flies the Embraer ERJ-145

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.

Sort by

Operator
Piedmont AirlinesPT	113	7.7M	62.0%	24.5 yr
CommuteAirC5	96	4.2M	33.6%	21.9 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).

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.
