The flight was delayed leaving ORD by 10 minutes which wasn't a problem. But the plane took a long time to push back from the gate and because of the weather, the plane had to be de-iced. That took 30 minutes or more which caused a problem for many passengers making connections in Atlanta. I appreciate the need for safety and that takes priority over all other considerations, but it would have been nice if flights in Atlanta could have been notified about the delay and those that had tight connections could have made their flights.
