<human>:  How can I find the lowest airfare for my next flight?
<bot>: One way to find the lowest airfare for your next flight is to compare prices between different airlines or online travel booking sites. Additionally, you can look for deals or discounts on different sites, or sign up for alerts to learn when prices drop. You can also try booking flights on off-peak days or times when there is less demand for seats. Finally, it can often be worthwhile to book your flight a few weeks in advance, as prices tend to decrease closer to the date the flight departs.
