I work for the other merged major airline, and you are 100% right. We do have a few schedule changes throughout the year, and sometimes flights are discontinued. From what I remember they should have contacted you for that big of a change. If its a few minutes here or here, a flight # change, or equipment change don't always expect a call. Glad to hear they accommodated you to the flight you wanted. I know my counterparts are in the process of making lots of changes to improve the airline.
