Human: What is the best way to find the best airfares? Assistant: 
The best way to find the best airfares is to compare different airlines and search sites, such as Kayak and Skyscanner. You can also sign up for email alerts from airline websites so you’ll be notified when there are deals available. Additionally, consider booking flights at least a few weeks in advance if possible, as this will usually give you access to the lowest fares.
