Tuesday, December 1, 2009, Flight #CO47 departing FRA at 1:30 PM arriving at IAH at 5:55 PM.

My wife and I were scheduled to return on the above mentioned flight. As CO is aware of the situation with this flight (confirmed through a letter we received), we were pushed back 24 hours and flew back on the same flight the following day. CO's arrangement for us (and the rest of the passengers, I assume) was a one-night stay at a hotel (the accommodations were satisfactory) and two meals consisting of dinner and breakfast (again, satisfactory). However, we were not kept informed on the situation by CO representatives nor were we provided telephone/communication opportunities.

Upon returning to Houston, my wife phoned CO to inquire as to any compensation arrangements that would be made available to us because of the cancellation of our original flight. Shortly there after, we were offered $250 in travel vouchers ($125 each). We found this unacceptable and did not accept the electronic voucher.

A few days later, I phoned CO in an attempt to get further information. After speaking with several people, I was promised a phone call back. No phone call was ever returned.

Two weeks later, I phoned CO again (the third time we've called the customer care line) and was on hold for over 45 minutes before speaking with someone who couldn't answer my question. My question is this: How does CO handle situations that fall under European Union Regulation 261/2004? Again, I was promised a phone call back by the customer care supervisor and no return call was ever made.

On January 15, I decided to send a message through the online customer care website. As it's been over 10 days, I still have not received any communication from CO.

EU Reg 261/2004 mandates certain rights that passengers have when flights are cancelled for non-extraordinary reasons. Our flight was cancelled for maintenance/repair, not because of an extraordinary reason. We believe that CO is solely responsible for this cancellation (this was not weather related, not related to other airlines, etc.).

As we've placed three calls to CO's customer care and one electronic message and have not received a response, we are curious as to what our next step should be. Any thoughts?
