Airbus A330 and Boeing 737 upgrades.
Both manufacturers stated at Farnborough they are now in a position to revamp 25 year old airframes. These will be fitted with new fuselage, new wings and new engines.
The whole package will be the 10th of the cost of a new plane with a 14% fuel improvement on todays aircraft.
Both manufactuers stated they will make more profit going down this route as against developing new generations of this series.
This would seem to encourage the business plan of Jet2 and be a logical way to increase the life of an airframe.
Both manufactuers saw only these two types as having the quantity flying necessary to put these plans in place.
Therefore we could in the next 25 years on this site have to either complain about a 50 year old airframe or check if it has had a revamp.
Both companies obviously have no issues putting their name and resources to encouraging airlines to keep them flying way passed todays old age.
