JetBlue has launched its most recent Go Pack for travel between Boston and all three Washington, D.C., area airports (DCA, IAD and BWI); $699 purchases 10 one-way flights between the cities, not including an extra $7 per-flight tax.

The Go Pack must be purchased by April 17 and reservations can be made starting April 20. There are a limited number of Go Packs available and the airline may sell out before April 17. As of press time, Go Packs were still available for purchase on JetBlue.com.

The purchaser will be awarded 4,200 TrueBlue points. Travel must take place between April 23 and June 27, 2012.

The Go Pack can be divided among multiple travelers, so it's possible to split the cost with family or friends. All seats on the routes are available for booking, meaning you'll only get shut out if the flight is 100 percent sold out before you make your reservation. However, the Go Pack only works on non-stop flights, so there's no way to make this work for a trip to New York City by booking a layover.
