Boeing 747-100 (United Airlines)
A United Airlines Boeing 747-100 in early colours.
A United Airlines 747-100 in the airline’s 1970s scheme.
This is the original 747 — six upper-deck windows rather than ten, and an upper deck used as a lounge before airlines worked out that seats earn more than sofas. More on the 747-100.
