Boeing didn't completely abandon the tri-jet variant of the 747. Instead of continuing development with three engines, the manufacturer created a shorter 747 with the conventional four engines. This was named the 747SP, with the suffix standing for 'Special Performance.'.

The then-designated A3XX project was presented in 1994; Airbus launched Metal fatigue cracks, source: Boeing. For long haul aircraft, that make relatively few cycles, the design lifespan is in the order of 40 000 cycles. For example, the Boeing 747 has a design number of cycles of 35 000, the MD-80 has 110 000. An aircraft should be operable for about 30 years before reaching the cycle limit.

It has also phased out most Boeing 737-800 delivered before 2014. The retired A340-300 and Boeing 747-400 are either stored at the aircraft boneyard at Victorville Airport or sold.

This means that the commercial jet must consider the environmental conditions, weight limitations, and the amount of fuel available for power.
