I have received the automated call from CO yesterday and today advising me of a schedule change that impacts my flight. Comes from an "Unknown number" and does not mention any specific flight information. I don't get a follow up e-mail advising me of any change. I'm like most of you and have over twenty flights listed on my Manage Reservations Tab. I don't feel like going in and checking every itinerary for a change. CO needs to change their system and have the automated message include flight information.
