First of all, thank you all for your advice and suggestions!! I received a message from USairways that they are going to refund the additional amount to my credit card. I think that they did the right thing!!

Here is the message i received:

Dear Mr. Nikolaos

Thank you for contacting Customer Relations at US Airways. We appreciate hearing from our customers and having an opportunity to address their concerns.

I apologize for the error when the agent was working to rebook your ticket. On your behalf, a refund request has been submitted to our Refunds Department for the additional fare. Please allow up to three weeks for review and processing. The refund will be credited back to the original form of payment. When a credit card is used for payment, it may take 1 to 2 billing cycles for the refund to be reflected on the statement. After allowing three weeks for the refund to be processed, you may check the status of your refund online. Please direct all future refund status inquiries to our Refunds Department using the following link:

We appreciate and value your business and are working hard to earn your continued patronage. I sincerely hope we have an opportunity to restore your confidence in our service.

Sincerely,


XXXX XXXX
Representative, Customer Relations
