"Reservation and cancellation fees apply to non-refundable tickets purchased at reduced rates. When such a ticket is purchased, we take that seat out of inventory. When it is released back into the inventory — often at the very last minute — we have lost our ability to sell it, and our fees offset some of the lost revenue.”  Perhaps I misunderstood this statement.  I presume non-refundable means you don't get a refund, hence the revenue has been secured.  Hence, how is this lost revenue?  Seems more like "lost opportunity" to resell seat...so revenue neutral?
