I just looked at the language that came with our package reservation confirmation. It says: "Guest will be responsible for any cancellation fees assessed by an airline. In the case of a non-refundable airline ticket, the cancellation fee is equal to the entire ticket price. Cancellation of a refundable airline ticket must be made at least 1 business day prior to guest departure." So unless you bought refundable tickets, it doesn't sound good as far as the airfare is concerned...
