Passengers

The number of passengers a specific aircraft can hold is based on a number of factors. 

One of these factors is the seating configuration. 

Larger airplanes can hold more passengers based on how the seats are arranged.

If the aircraft has first-class seating is available, it will hold fewer passengers versus a seating configuration without first class.

The larger the tanks, the more fuel they can carry.

Not all airplanes will carry the maximum amount of fuel on each flight

In fact, most commercial airliners fly without having full fuel on board. 

The Boeing 737-800 has a maximum fuel capacity of 26,020 gallons or 98,496 liters.

The Boeing 777-200 has a maximum fuel capacity of 31,000 gallons or 117,347 liters.

Therefore, the Boeing 777-200 can carry 4,980 more gallons of fuel than the Boeing 737-800.

Engine size

Commercial airliners like the B737-800 and B777-200 aircraft use different sized engines and each engine has a maximum rated amount of thrust. 

Not only is the physical size of the engine different between both airplanes, but so is the amount of thrust it produces.

The Boeing 737-800 uses CFM56-7B engines which produce 26,000 lbs of thrust each.

The Boeing 777-200 uses GE90-94B engines that produce 94,000 lbs of thrust each.

Therefore, the Boeing 777-200 engines produce 68,000 lbs of thrust more than the Boeing 747-400.
