Anybody actually think the 321xlr will become a real / good replacement for the 757 Europe stuff? Certification issues and overzealous performance numbers seem like that could be a stretch. If that doesn't work I imagine after 757's are stretched as long as possible then that flying will go to small 787's. Needing to take that big lift to put on former 75 flying wether it's not daily or whatever may create need for lift on the big side, hence 350's! Spitballing
