What is Boeing's reasoning in only providing one engine choice for the 777NG.
I would think that it would push airlines like SQ to Airbus since the A345 can be had with RR engines. I don't see why it benefits Boeing to only offer GE engines. Aren't there more RR customers than GE customers on the 777?

The 772LRs and 773ERs are niche aircraft so they won't sell in great numbers (like the A345/346), therefore it won't make sence to invest millions in developing 3 very expensive engines, if they would only sell a few.

One thing which may have been a deciding factor is that GE accepted to be a "risk sharing partner" in the 777X program. It was very comfortable for Boeing, which is not a seriously money strapped company, but certainly not sitting on a cash pile like GE.
P&W and RR would not have been able to make similar offers without acceptance from their banks, and it might be rather "expensive" to buy such an acceptance.
Always keep your number of landings equal to your number of take-offs, Preben Norholm

This thread hasn't exactly been bashing Boeing for their engine choice, but to answer your question- Boeing has a contractual obligation to only offer the GE90 on the 777LR, Airbus could find another engine supplier for the A340NG if it wished.. however no such engine exists or is in development.

Given only RR Engines are certified for the A340NG are there actually any other engines that are in operation that could be certified if the the engine manufacturer was prepared to fund Certification program?
