JetBlue has a flash sale going on. These are limited-time discounted fares valid for specific flights on specific dates/times and routes only. You can find starting prices from under $20 including taxes and fees. If you book with points it will cost you 400 points plus $5.60.
See full list of available flights and book directly at JetBlue.com. Act fast! In some cases, as seats are limited. There’s only three flights for $20, but there’s more deals for $30 and $40. All reservations made one week or more prior to a flight’s departure may be cancelled without penalty up to 24 hours after the reservation is made.
With some flexibility in your schedule and if you manage to find a good deal on a return flight, this could be useful. But most of these fares are midweek and either late at night or very early in the morning.
Keep in mind that these are all JetBlue “Blue” fares, which means that you’re only allowed a carry-on. You can also use a card like Chase Sapphire Reserve to earn 3x and get travel benefits such as free trip cancellation/interruption insurance, travel accident insurance, luggage insurance, trip delay protection and more.
