I imagine reasonable minds will differ, but I'm not entirely pleased with UA today. I was on an ORD-DCA early this afternoon, and my parents, who seldom fly were on a later ORD-DCA flight (due to award ticket availability). I was delayed 30 minutes, and my parents 2 hours due to "late arriving crew". FWIW, I am a construction attorney by trade, and I generally (based on well established case law) view the risk of not having ample staffing to complete a task as being allocated to the contractor. Certain force majeure events may come to bear, but they are the exception, not the rule. Moreover, I would expect an airline to provide for late arriving crew, especially at a hub such as ORD, where they can absorb scheduling irregularities better. Of course, I am aware that the cost of precautions gets passed onto the consumer, one way or another. But on balance, I posit that the risk of a crew from a, say, SAN-ORD not arriving on time to serve their following ORD-DCA should be borne by the carrier, as the risk of scheduling attends to their means and methods of getting the job done. And, yes, I'm a smidge upset that this is getting visited upon my parents, who no longer roll with the punches as they once did. Am I being unreasonable?
