Lux Flyer

There is nothing shady about what is happening. If you read the thread, or did a little bit of research, you would see the cancellations are occurring due to KLM widebody shortages. Instead of telling passengers they're SOL and leave them stuck with crappy alternatives, they are leveraging their JV and rebooking them on an additional segment being operated by DL at similar times, which reduces the issues with connections and EU compensation (as long as they depart no more than one hour earlier than scheduled, and arrive no more than two hours later than scheduled, they are due no cancellation compensation).. Essentially it is just a glorified equipment swap going on, but instead of being between KLM equipment it is with a JV partner, but because it is an operating carrier change they need to "cancel" the original flight and rebook on the alternative. Passengers are also entitled to refund their ticket instead of flying if they so chose, or request different arrangements; but I'd assume most would prefer getting to their destination under arguably the exact same travel conditions.
