Airline cancellations

We arrived at 4:45 am for our flight to find out that sometime after we verified the flight last night, it was cancelled.  Because no other flights  arrive in time for our connecting flight to Beijing, the soonest the airline can get us there is 5:00 am the next day.  If anyone knows how to get more than a $10 voucher for an additional 14 hours worth of travel time, let me know!
