Perhaps I said it wrong. The EU is a good example of how the regulation is clear. I wanted to say that if you can prove that they didn' t deliver the product as advertised but delivered another product you may have a claim to the difference if you can show that you would have " paid" less as miles are still considered a form of payment. This is true in any industry. The Delta COC isn' t clear on the difference between paid and award tickets either which could work in your favor if you take legal action.
