Maybe it's just a fluke in my survey of one, but it sure seems like the company is reducing the number of through flights. In the last month or two I have seen a lot more passengers that were on my inbound flight, reboarding the same airplane for our next flight (to include an entire college soccer team!) I haven't seen anything official out of the company on this, but it would definitely help with A-lister/Biz Select boarding satisfaction, and also the problem of FAs held hostage to thru pax on the plane.
