Long haul aircraft have fewer rotations per day and spend a larger proportion of their flying life at higher altitudes. Both of these factors tend to potentially make them longer lived (in years) than short haul aircraft.
Here are some examples, all based on aircraft bought by BA
732: Number of aircraft (for which full data is available) 21. Average life (from date of first flight to date of last BA
revenue flight) 6,433 days (17 years 7 months). Average number of flight hours 35,592. Average number of rotations 27,759.
741: Number of aircraft 14. Average life 9,708 days (26 years 7 months). Average number of flight hours 103,391. Average number of rotations 20,810.
742: Number of aircraft 16. Average life 7,328 days (20 years 1 month). Average number of flight hours 82,869. Average number of rotations 13,139.
752: Number of aircraft 37. Average life 5,665 days (15 years 6 months). Average number of flight hours 30,639. Average number of rotations 23,993.
I have not included types bought by BA
and still in service in the above. So, for example, BA
still operates many 734s but has already 'retired' 12 aircraft of this type.
Note also that the 732 figures may be greater than they would have been if BA
had not transferred many of them from their Main Fleet (Heathrow) and EuroGatwick fleets to BA
