British Airways has 18 Airbus A350-1000s, each with three classes and 331 seats. The equipment is renowned for its long range and large capacity, hence why it’s often considered a Boeing 747-400 replacement. It constitutes about 14% of the carrier’s widebody subfleet and 6% of its full fleet. Averaging 4.4 years, they’re its fourth-youngest aircraft after its Boeing 787-10s, A321neos, and A320neos.
