Okay, fair enough. Well, i think Lufthansa will consider boeing again, but i can assure you that beoing is not the first preference. LH now has a lot of infrastructure, which relvoves around Airbus common systems. In the A320 family and A340 and to a lesser extent, the A300 family. The effeciencies generated mean great cost savings to LH every year. Keep in mind that German labour is amoung the most expensive in the world, if no the most expensive. And, they work a 35 hour week, and in a crazy attemp to reduce unemployment, the government is pushing to reduce that to a 30 week. Thats expensive time thats not productive enough. So, where ever LH can save without sacrificing the product, it is bound to do.
So, if they have an airbus product and a boeing product, even if the Airbus comes at a slightly higher price it is in LH's interests to pay the extra. What would it take for LH to order boeing over airbus. Well, airbus would have to do something that really annoyed LH. I sincearly doubt this, i am sure Airbus would consider LH their number one customer. So, i don't see the 767-400 being ordered. The A330-200 can do it all, and will give commonality, not to mention that Lufhansa already owns the only slightly larger A340-200, which is with out a doubt the longest range airliner in the world. It would make the most sense for LH to simply order additional A340-200s, but, some time in the future they are going to need an aircraft for medium operations, to replace the A300-600. This is where the A300-200 is ideal. Its efficeny is best on the medium haul routes, but at the same time it has the ability if needed to really long range routes. Its size is very similar to the A300-600R. Well, its not needed immediately but this one seems to make the most sense. Then we have the Question of the A310 replacement. Well, i think LH will keep the A310s in service until airbus realese its A310 replacement. Who knows, its could be the A310-400. I don't think it would be wise to shorten the A330 anymore as its wing span is far to big for an aircraft the size of the A310. The Narrowbodies are out of the question, no need to say anymore especially with LH showing a lot of interest in the A318. And we know that the A340-600 has been ordered. Well, now we are in 747 size class. If the A340-600 can prove itself as an ultra long range aircraft, i think you will eventually see no boeings. But, this will take some time, and it is a big if, because the basic wing of todays A340 has to carry a lot more. The intial design really likens the A340-600 as a good 747-200 replacement. If this does not develop any further, i think you can say that LH will eventually order more 747-400s. Perhaps an extended range version, or one with more efficient engines. But who can tell - this one could go either way.
Then, we must consider the A3XX. Well, provided it does get off the ground they may decided to shorten it and then give us a 747-400 sized product that way too. Who knows, this one only time will tell. But, Anything under the A340-300 sized aircraft is not going to be a boeing. We would need some really big changes in commercial aviation to change that.
