for the future, you may want to consider using Orbitz for the
search of the flights that you want, write down the flight numbers
and then go to the airlines directly to purchase.
Also,
www.site59.com is a great place to purchase last minute
flights...they put packages up there at really good prices...
however these will be non-refundable, but great in a pinch and
much cheaper than purchasing direct from the airlines at the
last minute
