That 800EUR was per person. Initially, they were offering 300EUR compensation for everyone, who accepted the change to HiFly. First they refused the to pay us the compensation (reasoning that since we were on AA award tickets, none of their business..?!), then they agreed to pay, then they changed the amount to 150EUR pp, after which I escalated the claim in their hierarchy to the next level, which then agreed to pay the original amount of 300EUR pp. And all this before we even set foot on the HiFly aircraft. After the flight I sent in another complaint due to pure crap experience, and they agreed to pay 100EUR more pp without any questions.
