JetBlue is back this year with its Big Spring Sale, featuring Monday-Thursday one-way flights starting at $49. Flights are available across the JetBlue network — domestic and international destinations — for travel through mid-June.

Deal basics

Airline: JetBlue
Routes: Across the JetBlue network
How to book: Directly through the airline
Travel dates: March 18-June 11
Book by: 11:59 p.m. EST on March 6
Blackout dates: Excludes Friday, Saturday and Sunday travel; additional blackout dates may apply depending on the route

Sample flights

The following one-way flights were available at the time of publication. We cannot guarantee availability when you book:

• John F. Kennedy International Airport (JFK) to Palm Beach International Airport (PBI), from $49
• Orlando International Airport (MCO) to LaGuardia Airport (LGA), from $49
• Boston Logan International Airport (BOS) to Tampa International Airport (TPA), from $59
• Luis Muñoz Marín International Airport (SJU) to Cibao International Airport (STI) in the Dominican Republic, from $69

• JFK to Rafael Hernández International Airport (BQN) in Aguadilla, Puerto Rico, from $89
• JFK to San Francisco International Airport (SFO), from $119
• JFK to Aruba’s Queen Beatrix International Airport (AUA), from $129
• JFK to Punta Cana International Airport (PUJ), from $149

For this deal, you can search flights from a specific destination or view the routes broadly. Sale prices include all government taxes and fees and are for the lowest available fare — either Blue Basic or Blue. Change and cancel fees apply to Blue Basic fares, so consider upgrading for further flexibility.

Though this sale advertises one-way flights, you might be able to stack two discounted one-way flights to book a round trip.

Maximize your purchase

If you book this deal, consider using a credit card that earns bonus points on airfare purchases, such as:

• American Express® Gold Card: Earn 3 points per dollar spent on airfare when booked directly with the airline or through American Express Travel.
• The Platinum Card® from American Express: Earn 5 points per dollar spent on airfare when booked directly with the airline or through American Express Travel (on up to $500,000 of these purchases per calendar year, then 1 point per dollar).
• Chase Sapphire Reserve®: Earn 3 points per dollar spent on airfare.
• Chase Sapphire Preferred® Card: Earn 2 points per dollar spent on travel.

Citi Strata Premier℠ Card (see rates and fees) cardholders booking this deal should check their Citi Merchant Offers to see if they’ve been targeted for a Citi Merchant Offer for $25 back on JetBlue purchases of $250 or more. This offer cannot be combined or stacked with other offers.

Bottom line

JetBlue’s Big Spring Sale is available to book for travel starting later this month through June. Book by Thursday to take advantage of these low fares.
