Usdot is concerned by Southwest’s unacceptable rate of cancellations and delays

EU regulations go even further than that. Even if the flight isn't cancelled, delays can mean that they need to provide a replacement flight and still must compensate you. I was once denied boarding and they comped me an overnight stay at a hotel with breakfast, I was reimbursed for my flight, and they gave me the next morning flight to my destination.

There isn’t compensation for this in the US? I don’t think I’ve ever had a flight cancelled.

They’re dropping down to 1/3 of their capacity to get scheduling back on track.
