I booked a trip to Paris for 4/1 using United Miles(business class)- they booked us on Lufthansa to land in Paris at 8:00 a.m. Got a phone call last night that Lufthansa was cancelling the flight. United rebooked us on a much later flight to Munich with a 4 hour layover and then Munich to Paris landing at 4:25 p.m. We lose an entire day in Paris. I called United 5x between last night and today and there are absolutely NO award seats (in any class) available on the dates. I really needed to be in paris before early afternoon. I called Air Canada to no avail. Anyone have any suggestions. The United people told me to call them every week to see if any seats open up.

Can anyone give me any suggestions on what to do.
Thanks.
