Surtout la part historique ... les 9-10 % d'écos dans les cas cités, avec un prix du fuel beaucoup plus bas !
Donc, attention, tout est très lié au coût du kérosène et today ...
Bien que l'auteur s'abstienne de conclure !

BRUSSELS (AP) - Airbus says it has no plans to replace its A320 family of medium-range passenger jets before 2025 despite competition from new manufacturers.
Airbus senior Vice President Rainer Ohler said Tuesday that a new project costing about euro10 billion ($13 billion) would not be justified unless it could offer a 25 percent increase in overall performance. He says new technologies needed to achieve this target are not available.
Airbus' rival Boeing Co. has been mulling the replacement of its 737 family — the best-selling airliner ever — while Airbus is developing the A350 long-range jet liner and A400M heavy military transport.
Airbus is still working on the newly introduced A380, the largest passenger jet in the world.

PARIS — Airbus a lancé officiellement mercredi son projet A320 NEO destiné à offrir en option de nouveaux réacteurs réduisant la consommation de carburant, sur la famille de ses moyen-courriers A320, qui devraient être livrés à partir du printemps 2016.
"Les clients pourront ainsi bénéficier d'une réduction de la consommation de carburant pouvant atteindre 15%", écrit Airbus dans un communiqué.
L'avionneur prévoit un marché potentiel de 4.000 appareils de la famille A320 NEO au cours des 15 prochaines années.
Les compagnies auront le choix entre la motorisation LEAP-X de CFM International - coentreprise entre le français Safran et l'américain General Electric - et le PurePower PW1100G de l'américain Pratt & Whitney.
Comme l'avaient indiqué mardi soir des sources proches du dossier à l'AFP, Airbus annonce qu'il livrera les premiers exemplaires de la famille A320 NEO à compter du printemps 2016, et non en 2015 comme initialement envisagé.
Ils seront aussi doté d'ailettes verticales à l'extrémité des ailes, baptisées "sharklets", destinées à réduire la consommation en carburant.
L'investissement pour ce projet n'a pas été précisé mais serait de l'ordre de 1,2 milliard d'euros. Le conseil d'administration de la maison mère EADS a donné son feu vert au projet.
Bombardier CSeries launch customer Lufthansa is among several airlines and lessors interested in ordering the newly-launched Airbus A320neo.Speaking to ATI today, Airbus chief operating officer for customers John Leahy said there were "no orders in hand right now" for the A320neo, but talks are taking place with Lufthansa, AirAsia, Qatar Airways, International Lease Finance Corporation (ILFC), GECAS and IndiGo, all of whom are "very interested".Leahy says Airbus does not need a launch customer because the A320neo is "not a typical" launch programme."It's not important how many we sell as Neo, it's how many A320s we sell," he notes, adding that whether customers order existing A320-family aircraft or the Neo version is "immaterial".Airbus does not expect customers with existing orders for A320-family aircraft to switch to the A320neo."Virtually nothing in our backlog will convert to the Neo," says Leahy, but he expects "a large portion" of new A320 orders for deliveries in 2016 and 2017 to be for the Neo.Lufthansa was not immediately able to comment.

Rolls-Royce is confident it will have a competitive offering available when new narrowbody aircraft programmes are launched in the future, despite its absence from the Airbus A320neo programme."We have been unable to construct an acceptable business case for re-engining and have elected not to participate in the A320neo," says a Rolls-Royce spokesman."We continue to have the technological and financial resources to support this and other sectors and we are confident that we will have the competitive product and service offerings available when our customers launch new aircraft programmes in the future."The manufacturer declines to comment on the future of the International Aero Engines (IAE) consortium, which comprises Rolls-Royce, Pratt & Whitney, MTU and Japanese Aero Engine Corporation.P&W broke away from IAE to offer its geared turbofan engine to Airbus after failing to reach consensus on a new product offering with its IAE partners.

The A320 will be the first model to offer a Neo version when it enters service in spring 2016, with the A321neo set to follow six months later.
The A319neo will be the last model to be made available under the new programme, although no firm date has been set.
Airbus has not set a cut-off date for when existing A320-family models will no longer be available.
"I would envision that you could always order an A320 with the existing engine if there is enough demand," says Leahy.
However, he points out that "at some point in time" it will make more sense for customers to order the Neo because of the weight savings the new engines offer on the new airframe over models powered by International Aero Engines V2500s.
Excluding engines, nacelles and pylons, the airframe for the A320neo will be 250-300kg (550-660lb) heavier than the current A320 airframe.
