Bit of both I think. Also I can really only speak to one route that I fly *way* too often (YYC-YYZ). But there has been a lot of tinkering with schedules in terms of frequency of flights and equipment used. For the last 6 months it has changed every few weeks or so. Somebody is doing a lot of experimenting to try and find the optimal mix of equipment and schedule. As a frequent flyer, this isnt always a good thing (I would much rather have hourly service on a 319/320 than every 2 hour service on a 321, for example). But I bet it is a really good thing for profitability. Load factors are definitely way up on this route.
