Has US Airways Changed From Visa To Mastercard?

It seems that US Airways has changed from VISA to Mastercard in regard to providing services to US Airways Dividend Miles customers. This morning a top search in Google usairwaysmastercard.com/enroll raised this question.

As our team member visited usairwaysmastercard.com/enroll he saw the following message regarding to "Former US Airways Visa Customers."

The message reads that "if your Visa card account was recently transferred click here to set u online access. The word "transferred" is the key. What does it mean?

Probably US Airways is now using MasterCard. Thus, the airline has set up a transfer website usairwaysmastercard.com/enroll for the former Visa card customers.
