I noticed the price drop as well...it was very very low for about 3 days, about $200 per ticket lower than the $570 we paid when we booked. The cheaper flights, however, are not the ideal flights. In order to get the better deal we would have an overnight connection on the way home, if not on the way there as well. When I priced our package rate through the Couples site and tried to compare before booking our airline separate, I also noticed that the flights that Couples would have had us on were an overnight, so the price difference was a cheaper flight, but also one less night at Couples. Not worth it for us.
