<human>:  I'm trying to figure out the best time of year to book a plane ticket. Can you help me out?
<bot>: Well, the best time of year to book a plane ticket can vary depending on a few factors. These include the destination, the airline, and the season. Generally, for most flights, the winter months tend to be the cheapest for airfare. If you plan well in advance, you may be able to find some great deals in the spring and fall.
