Not seen means AwardTool hasn't observed this cabin on this route in the last 30 days. It doesn't mean the airline has no seats. Dates seen counts departure dates with an open award in that cabin at any price; newest observation is the latest time AwardTool saw one of them. Seats is the count the program reported when we observed it; some programs report at most 9.
Prices are one-way per traveler: the program's points or miles plus taxes and carrier fees in USD, as AwardTool observed them in the observation window. Award space changes constantly. A seat we saw may be gone, and space we haven't seen may exist. Always confirm with a live search before transferring points; most transfers can't be reversed.
