I have had the exact opposite experience. I am flying 2-4 days a week at the moment and 99% of the trips are delayed, cancelled or misconnected. Case in point yesterday. PDX-DEN delayed 40 minutes due to late inbound crew. That made my connection 8 minutes. Land in DEN at the time my plane to NY is departing. They didn't hold it for me even though I'm a 1K in first class on the last flight of the day. The most the plane would have had to wait was 10 minutes. So I misconnected and was forced to overnight in DEN. Sure, that's just one example. But every single flight I'm on is delayed (usually late inbound).
To me this has been the Summer of Hell that they were advertising a few years back.
