Boeing 767 vs. 777: Key Differences in Range, Capacity, and Efficiency
Boeing 767 is a twin-aisle, medium-range jet seating 180–250; Boeing 777 is a larger, long-range aircraft carrying 300–400+ passengers on intercontinental routes.
Passengers see similar twin-aisle cabins and assume they’re the same plane. Airlines often swap them on the same route, and both names start with “7,” making the distinction easy to overlook at the gate.
Key Differences
767: 5,800 nmi max, 2 engines, lighter, better for thinner trans-Atlantic runs.
777: 8,500 nmi max, 2 bigger engines, heavier, built for Pacific non-stops and high-demand hubs.
Which One Should You Choose?
Pick 767 for lower demand or shorter long-haul; choose 777 for packed routes needing cargo and ultra-long legs. Your ticket price and schedule already reflect this choice.
Examples and Daily Life
You flew Delta 767 to London last year; this month, the same flight is a 777. Same gate, bigger overhead bins, more lavatories, and likely a higher seat count.
Can airlines swap a 767 and 777 on the same route?
Yes, if passenger and cargo loads justify the larger 777; schedules are flexible.
Which burns less fuel per seat?
The 777-300ER edges out the 767-300ER on fuel per seat when full, thanks to newer engines and scale.
