There seems to be a pattern here with 757's. After two days of mechanicals (SEA-DTW-SEA) including one cancellation and another aircraft replacement I was talking to some DTW flyers.

According to a couple of them, the 757 flights into SEA and PDX seem problematic regarding mechanicals. Frequent cancellations. Mostly engine-related.

Yes, it's unscientific. But is there something here?
