Like someone else said, Copa is pretty much always offering $400 vouchers for bumps. I haven't been bumped for about a year now but the last time I was bumped was on the LAX-PTY flight (which when it was 1 flight/day was oversold everytime I flew it) and they put me up at an airport hotel, gave me meal vouchers and a $400 voucher. They also put me on AA in Business class from LAX-MIA-GYE the next morning so I only arrived about 8 hours later than I was scheduled to arrive and got to fly Business Class.

As for the Copa voucher, they kind of stink compared to other airlines vouchers. For one, they are paper vouchers (or were a year ago) and they need to be redeemed at a ticket counter at an airport (which isn't convienent when the nearest Copa ticket counter is a 3 hr flight from me!). Another issue with the voucher is that it doesn't cover Taxes! It also is only redeemable at the ticket counter which makes web only fares impossible to book. I was pretty disappointed with the vouchers but everytime I took a bump on Copa I was taken care of very well. I asked for Business class everytime and they did it for me (maybe because I was a Plat at the time). Even when they booked me on other airlines they would give me my original routing credit, so I got miles for not even flying them....and also miles from the other airline I flew with 50% bonus for fare class. Personally, I think that a $400 voucher for a 1 day delay and a 7 hour flight is weak but if you are a smart traveler, you will have them book you in Business Class and get you where you are going as fast as possible.

ALSO: Just a note that MODS should consider moving this to the Continental OnePass forum because Copa uses COs OnePass program and this may get a better response there!
