Today, Jetblue opened the floodgates to spooky $31 fares for flights on Halloween day. Fares can be booked today or tomorrow for flights on 10/31 only, until sold out.

We checked a handful of routes and availability appears to be wide open. Great deal for the outbound leg of a last-minute getaway this weekend.

To take advantage of this deal, plug your routes into the Best Fare Finder. Or check out the full list of routes here.
