JetBlue Baggage Fees

JetBlue baggage fees run $45 for a first checked bag and $59 for a second on off peak dates. Both prices jump by $4 to $10 the moment your travel falls inside JetBlue’s own peak calendar. That calendar swing is the part most travelers miss when they price a trip months out.

JetBlue baggage fees are not one flat number. They move with the season, the fare you bought and which card is in your wallet. The peak calendar itself is public and worth checking before you buy.

JetBlue lists specific date ranges each year as peak. Roughly late spring through late summer counts, along with Thanksgiving week, the winter holidays and President’s Week. Fly outside those windows and you land on the lower, off peak row of the table below.

JetBlue baggage fees by bag and fare

These figures come from JetBlue’s own Optional Services and Fees page, current as of this writing. Every price below covers flights within the US, Latin America, the Caribbean and Canada. Transatlantic routes use a separate, higher scale, covered further down.

A third bag costs $200 on every domestic and near international fare or status. Prepaying the first two bags online saves $4 to $10 per bag versus paying at the airport. Prepay at least 24 hours before departure to get that discount.

JetBlue also lets you cover a bag fee with TrueBlue points inside Manage Trips. Basic Economy on most US airlines strips out a free carry-on. JetBlue’s own baggage rules confirm Blue Basic keeps a full free carry-on and personal item.

It is checked bags, not the cabin bag, where Blue Basic pays full price. That distinction trips up a lot of first time JetBlue flyers. See the JetBlue baggage rules page for the carry-on and personal item allowances.

Transatlantic bags use a separate scale

Flights across the Atlantic price bags in dollars, pounds and euros together. The first bag is included on Main and EvenMore fares, but not on Main Base or EvenMore Base. Main Base and EvenMore Base pay $75 off peak or $85 on peak dates for a first bag.

A second bag on those fares runs $109 off peak or $119 on peak dates. A third bag on transatlantic routes costs $200 off peak and $210 on peak dates. Mint and Mosaic 2 through 4 travelers still get both bags included.

JetBlue caps checked bags at two on flights to and from Ecuador. The same two bag cap applies from mid November through mid January for Guyana, Haiti and Trinidad and Tobago. That limit holds no matter what you already paid for a third slot elsewhere on the network.

Overweight and oversize fees

JetBlue charges weight and size as separate line items. A bag that is both heavy and too large gets billed for both. A bag between 51 and 99 pounds costs a flat $150 to check.

That $150 applies whether the bag weighs 55 pounds or 95. Anything over 99 pounds gets refused outright. Oversize works the same way.

A bag measuring 63 to 80 linear inches, meaning length plus width plus height, costs $150. Anything past 80 inches will not be accepted at all. Bags checked to the Dominican Republic, Haiti or Port of Spain that hit either overweight band get refused rather than charged.

All of these charges get collected at the airport during check in, not in advance. A 51 pound bag and a 95 pound bag cost the exact same $150, so there is no reason to guess at home. Weighing a bag with a digital luggage scale before you leave is the cheapest way to skip that surprise at the counter.

Our overweight and oversize baggage fees guide breaks down how carriers set these bands across the industry.

What waives the first bag fee

Three things get a first checked bag included on every JetBlue fare except Main Base. TrueBlue Mosaic status does it, and so does the JetBlue Plus Mastercard or the JetBlue Premier Mastercard. Mosaic 2 through 4 goes further and waives the second bag too, for everyone on the same reservation.

The two co branded cards cover a first bag for up to three travelers on the same itinerary. That waiver only applies on JetBlue operated flights. A codeshare or partner operated segment does not qualify, so check the operating carrier before you count on it.

Our roundup of credit cards that cover baggage fees compares the JetBlue cards against what other carriers offer.

How JetBlue compares to its rivals

JetBlue’s $45 off peak first bag sits close to what Delta Air Lines and American Airlines charge domestically. It runs well under what Frontier and Allegiant collect for a bag added at the gate instead of online. The real gap is the peak surcharge and the flat $200 third bag fee.

Few full service rivals price a third bag as a flat number the way JetBlue does. Spirit Airlines is no longer part of that comparison, since it stopped flying on 2 May 2026. Travelers who used to weigh JetBlue baggage fees against Spirit’s a la carte pricing should compare it to Frontier or Allegiant instead.

How to travel cheaper on JetBlue

Add checked bags during booking or from Manage Trips at least a day before departure rather than at the airport. That alone saves $4 to $10 per bag. Families who check two bags on more than one trip a year often recoup the JetBlue Plus card’s annual fee within a couple of round trips.

Packing to stay under 50 pounds matters more than packing light for its own sake. The fee holds flat all the way to 99 pounds, then refuses the bag entirely past that. A soft sided bag that compresses a few inches has a better shot at the 80 inch oversize cutoff than a rigid hardside packed to its limit.

Our guide to avoiding baggage fees covers more of these tactics across airlines. JetBlue’s own carry-on weight limit page is worth a look before you decide what goes in the cabin instead of the hold.

The bottom line

The cheapest honest way to handle JetBlue baggage fees is to prepay online outside the peak calendar. Hold Mosaic status or a JetBlue co branded card for a free first bag whenever you can. Weigh every bag at home so it never crosses 50 pounds, and the $150 overweight charge and the $200 third bag fee never come into play.
