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.
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.
