JetBlue has a flash sale going on. These are limited-time discounted fares valid for specific flights on specific dates/times and routes only. They have low starting prices, 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 five flights for $20, but there’s more deals for just a bit more. 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. You can grab a flight from Boston to NYC for example for just $19.53. That’s super cheap.
Keep in mind that these are all JetBlue “Blue” fares, which means that you’re only allowed a carry-on. If you need to check in luggage, fees just went up. It’s now $30 for the first and $40 for a second luggage.
