I think the benefit of engine swaps is far overrated. How many airlines operate more than one engine type for a plane? Those that do buy their planes second hand so are highly unlikely to buy the 7E7. Those airlines that can afford the 7E7 make it a point to standardise on one engine type per aircraft type. Preferably even one engine type for various aircraft types.

As the article mentioned the leasing companies are going to appreciate this. No denying there. But how often does a plane change airline? Probably not often enough to warrant the additional costs, since most leasing contracts are long term.

Still, can’t wait to see this plane hit the skies!

You’d be surprised how many owners a plane can have in its life. There are 757’s that are already with the 5,6,7 or even 8th owner.

The whole point of the interchangable engines is to make the 7E7 a more attractive investment as an airline will be able to sell it off more easily if you can sell it second hand with a choice of engine. In one fell swoop, Boeing have limited the depreciation value.

For example. Take BA’s 767’s. They can’t sell them for love nor money because they use RR engines. No on wants RR engines on the 767. If however you could simply swap them for PW’s or GE’s within 24 hours the 767 would instantly become saleable.
