If you have a flexible schedule, you may want to take advantage of the app's "Flex Dates"* feature in order to find the best deals!
After selecting a specific month or a specific date range from the calendar view, you will have the option to "See Flex Dates."
When selected, you will be shown prices for a variety of different date ranges, which you can choose and continue through the booking flow with. You can also set a notification to "Watch All" to receive price predictions if you're not quite ready to book yet.
*Please note that this feature is currently only available on iOS.
