This year, for example, prices for delta, which we typically use, have been high and haven't changed much.
If this happens far in advance of your flight (as in, a week or more), you should start with the airline through which you booked, even though the flights are being operated by a different carrier. Avoid booking flights in may, where prices can be up to 6% more than the average yearly flight price. When using your points, though, you can only book up to 270 days in advance.
