I agree with the OP on this and was just about to start a thread on exactly the same point.

The listing of the old and the revised flights without identifying which is which is a frustration that could surely be avoided.

In addition, I see ABSOLUTELY NO reason why in this day and age when the airlines are trying desparately to have us NOT pohone agents that any schedule change REQUIRES a phone call to "accept". Surely a radio button "I have received and accept these schedule changes" on the website would make things MUCH simpler.

Instead I am tying up agents' time reading back to me the changes I have already seen on the website when they should be helping the poor pax stranded around the country (globe) as a result of the snow in DEN.

Merry Christmas all
