The deal was too good to be true.
I just got this email:
Dear Orbitz traveler,
Thank you for choosing Orbitz as your preferred travel provider. We regret to inform you that, due to limited availability, the airline was not able to confirm the flights you requested. Therefore, no tickets have been issued for this trip and your credit card has not been charged.
Situations like this are rare; however, when they do occur we attempt to contact our customers immediately as to avoid missing out on advance purchase opportunities. To book a different flight, please visit
www.orbitz.com
To help you understand how this situation could occur:
Orbitz is a full service travel agency. Our advanced search engine searches two billion fares within seconds from over 450 airlines. Our secure on-line booking system accesses fares and availability from the same central reservation systems that other travel agents and airline reservation agents are booking from worldwide. As you can imagine, with the extensive volume of agents booking flights at any given time, availability for a particular flight can be gone in an instant. Therefore, when your ticketing request reached the airline, availability for the flight(s) you selected was no longer available.
The confirmation e-mail that you may have received is only an acknowledgement that the flights you selected for purchase have been sent to the airline for approval prior to ticketing and does not guarantee ticket issuance.
We apologize for any inconvenience this may have caused and look forward to serving you in the near future.
Sincerely,
Orbitz Ticket Advisory Department
I would rather pay $130 US and go to Spain. 
We decided to just go with one week -- if you're thinking about making a longer trip to see other parts of Europe, you can book for 3 weeks (Sept 7 to 28).
