This is the first time I've heard about this as a tool for IRROPS recovery. And assuming the 65 PAX is true, UA made a brilliant decision that was the best compromise for its passengers and itself. I researched the flights and times of UA and others Monday, and this was by far the best option for them. It can throw the IAD passengers a bone for the inconvenience, but I bet very few passengers would be too upset. They know what it's like to be in those shoes. Good to see UA do something like this.
