No, the airport manager didn't explain. I assume it was because I had been pretty vocal on social media, expressing my concerns about unreliability. They wanted to put best foot forward and they did.

Re: Compensation: 1) I was offered a free round trip which I have already booked. E-ticket is in hand for Paris in August, 2) I was told they would reimburse my hotel bill within 30 days. We are no where near that so stay tuned..., 3) I also have a voucher in hand for $600.00 to apply to another ticket within the year. So far they have honored all commitments promptly and with courtesy.
