If CNN/Reuters have it right, the DOT proposal only contemplates $100 in cash compensation for delays in excess of 3 hours, which would be a lot less generous than EC261 and the associated Right to Care enjoyed by European air consumers. I'm not really sure if this is going to impact airfares to a meaningful degree.
