Additionally, the cabin height of the 747 is around 7 feet, providing ample headroom for passengers.
On the other hand, the Boeing 777 has a slightly narrower cabin compared to the 747, with a width of approximately 19 feet. However, it still offers a comfortable amount of space for passengers to move around and relax during their journey.
The cabin height of the 777 is also around 7 feet, ensuring that passengers have enough headroom.
Passenger and Cargo Capacity
When comparing the Boeing 777 and Boeing 747 jumbo jets, one of the first factors to consider is their passenger and cargo capacity. The Boeing 777 has a maximum seating capacity of up to 550 passengers, depending on the model and configuration.
This makes it an ideal choice for airlines operating long-haul flights with high passenger demand.
On the other hand, the Boeing 747, also known as the “Queen of the Skies,” has a larger passenger capacity compared to the Boeing 777. The latest model, the Boeing 747-8, can accommodate up to 467 passengers in a typical three-class configuration.
However, some airlines have configured their Boeing 747s to carry even more passengers, with a maximum capacity of over 600.
When it comes to cargo capacity, the Boeing 777 is designed to carry a significant amount of cargo in addition to passengers. It has a spacious cargo hold that can accommodate up to 7,825 cubic feet (221 cubic meters) of cargo.
This makes it a popular choice for airlines that need to transport both passengers and freight on long-haul routes.
The Boeing 747, with its iconic hump, offers even greater cargo capacity. It has a cavernous cargo hold that can hold up to 16,700 cubic feet (473 cubic meters) of cargo. This makes it a preferred choice for airlines that prioritize cargo transportation, such as freight carriers and those operating in the air cargo industry.
It is important to note that both aircraft models can be configured with different seating and cargo layouts, allowing airlines to customize them according to their specific needs. Therefore, the exact passenger and cargo capacity may vary depending on the airline’s configuration choices.
