I got an automated voice phone call from CO "your upcoming flight with CO has had a schedule change. please call CO or check on co.com".

Problem is - it does not give you the departure date. I always have about 10 trips booked in the hopper - so I do I know which one it applied to?

I noticed a slight change on a flight departure time on one record the day before and I accepted it. Since that was the only recent change - I assume the next day call around 6pm was related to that accepted change. Maybe CO times its automated calls for dinner time / after work?

Anyway - CO if you can add the departure date to the automated voice call - please do - it would help.
