Cheap flights from Boston to Key West
Are you ready to book your flight, but feeling nervous about paying too much if the price drops? Don't play the waiting game. Our Best Price Guarantee means if you see a better fare for the same flight, we'll give you the difference in CheapCash, plus a $50 CheapCash bonus, which you can use to save on your hotel reservation.
If you have a frequent flier account, add it to your reservation to earn miles. And don't worry about getting stuck in a middle seat. Choose your seats when you book, so you'll be right where you want to be on departure day.
