I have been getting the same message since early yesterday evening. While I understand that the hubs are getting a lot fo snow and thier are a lot of cancelled flights and many people are calling, this is not an unusual situation, it happens many times every year. One of continentals main call centers is in houston where it hasn't snowed, and with global call centers they should be able to handle the extra volume.

While I don't expect immediate response I do expect to be able to get through and hold a reasonable period of time and get through to a person. I tried calling very late last night when call volumes are typically very low and got the same message. I also happened to call usair right afterwards (as my flight is on usair metal) who answered the phone without any hold time, and rebooked my flights, now i just need CO to reissue the tickets.
