American Airlines has offered power to passengers, but US Airways didn’t. In fact, after America West acquired US Airways they removed power from the US Airways planes that already had it. The idea was to reduce weight and save fuel.
It’s been over three years since the American Airlines – US Airways merger. They’ve combined frequent flyer programs and reservation systems. They’ve bought back billions of dollars worth of stock. But most US Airways planes still have the same interiors — no Main Cabin Extra (extra legroom seating in coach) and no seat power. There hasn’t even been an announced plan to change domestic Airbus aircraft other than the A319s.
