This is on their website concerning my cancelled flight LAX-CDG. The do not mention cash refund. Would my credit card company reverse the charge. I see upstream on this post some FAA regulation mandating refunds for cancelled flights (?) These were pretty cheap seats - $717 RT. Are they stating that any rebooking with be the same price?

Seats not available on every flight—other restrictions may apply.
