Which one is better, Boeing 738 or Airbus A321?

Boeing 738 and Airbus A321 have different functions. Looking at the number of passengers, Airbus A321 is better.

Boeing 737-800 is one of the Boeing 737NG. The new generation of Boeing 737NG includes Boeing 737-600/Boeing 737-700/Boeing 737-700ER/Boeing 737-800/Boeing 737-900/Boeing 737-900ER/Boeing 6 models are improved products of the traditional Boeing 737 aircraft.

The Airbus A321 is a twin-engine short- and medium-range passenger aircraft developed by the European company Airbus Industries, and is an extended version of the Airbus A320. It is the largest aircraft member of the A320 family of aircraft. Compared with the A320, it has 24% more seats and 40% more space, slightly expanded wing area, added two emergency exits at the front and rear of the wing, reinforced landing gear, and uses high-thrust CFM56 and V2500 engines. If it is a high-density cabin layout, it can accommodate up to 220 passengers.

In terms of time, Airbus is a rising star. Boeing was founded in 1916 and has gone through the military, commercial and civilian eras. In the field of civil aviation, Airbus is its biggest competitor, and Boeing is Boeing's latest market outlook last year, one of the largest U.S. exporters that operates the U.S. space shuttle and the International Space Station, predicted significant growth in China's commercial aircraft business.

The A321 fuel system is completely different from that of the 320 and 319. The 321 aircraft does not have a central tank booster pump, only two ejection pumps. Therefore, the fuel supply method of the 321 aircraft is always the central fuel tank-large wing fuel tank-engine. The central fuel tank cannot directly supply fuel to the engine. This is to prevent fuel pollution. If two engines use fuel from one tank at the same time, if the fuel is contamination, both engines will be at risk, so they should be separated to ensure a safety margin.
