There is no generic seating chart for a Boeing 757 aircraft, but SeatGuru.com and SeatMaestro.com offer some examples of common seating configurations in their seat plans for American Airlines and Delta Airlines 757 domestic and international flights. The 757 is a single-aisle narrow body jet that carries up to 295 passengers.
A typical 757 seating plan for domestic flights comprises six pairs of first-class seats, between five and nine rows of extra legroom seats arranged in threes either side of the aisle and from 17 to 23 rows of economy seats also set out in groups of threes. Restrooms are located at the back of the plan and to the front and rear of the first-class section. The seating plan for international flights is very similar except for the front section, which has four rows of lie-flat business-class seats.
