Verdict: On most JetBlue fares, the first checked bag is $39 prepaid (24+ hours out) or $49 inside 24 hours, with a $10 peak surcharge during busy travel periods. Blue Plus passengers get the first bag free. The JetBlue Plus card also waives the first bag for the cardholder and up to three companions.
JetBlue charges $39 for the first checked bag when you prepay at least 24 hours before departure on most domestic fares, as of July 2026. Wait until within 24 hours of departure and that rises to $49. During JetBlue’s peak travel periods, add $10 to either of those numbers. Blue Plus passengers get the first bag free at any time. The second bag costs $59 prepaid off-peak, or $69 during peak dates.
Those are the numbers most people come here for. The rest of this article covers what “peak” actually means in practice, which fare classes include bags, how Mosaic status and the JetBlue Plus card change the math, and what happens when your bag is overweight or oversize.
All figures below come from JetBlue’s published optional-services fee schedule and were verified for this article in July 2026. JetBlue updates its fees periodically, so check jetblue.com before you travel for the current numbers.
This covers flights within the contiguous United States, Alaska, Hawaii, Puerto Rico, the US Virgin Islands, Canada, the Caribbean, and Latin America, as of July 2026.
| Bag | Off-peak, prepaid (24+ hrs) | Peak, prepaid (24+ hrs) | Within 24 hrs of departure |
|---|---|---|---|
| 1st checked bag | $39 | $49 | Add $10 to whichever rate applies |
| 2nd checked bag | $59 | $69 | Add $10 to whichever rate applies |
| 3rd checked bag | $200 | $200 | $200 |
The off-peak/peak divide is the single most confusing part of JetBlue’s baggage pricing. A traveler buying a bag in March for a June flight should assume peak pricing applies to summer travel. JetBlue officially designates peak periods as late April through early September, mid-October, late November through early January, and mid-February. If your travel falls in any of those windows, use the peak column.
The $10 late-add fee applies on top of whichever base rate you face. If you forget to add your bag until the day before a summer flight, you pay $49 base plus $10 late, equaling $59 before you even touch the overweight table.
JetBlue sells five fare categories on most routes. What you pay for a checked bag depends entirely on which one you booked.
| Fare class | 1st checked bag | 2nd checked bag |
|---|---|---|
| Blue Basic | $39 off-peak / $49 peak (prepaid) | $59 off-peak / $69 peak (prepaid) |
| Blue | $39 off-peak / $49 peak (prepaid) | $59 off-peak / $69 peak (prepaid) |
| Blue Extra | $39 off-peak / $49 peak (prepaid) | $59 off-peak / $69 peak (prepaid) |
| Blue Plus | Free | $59 off-peak / $69 peak (prepaid) |
| Mint | Free (2 bags, up to 70 lbs each) | Free |
Blue Basic, Blue, and Blue Extra all pay the same checked bag rate. The only meaningful bag benefit in the standard tier structure is the jump to Blue Plus, which covers the first bag at no charge.
One thing Blue Basic passengers lose beyond bags: Blue Basic does not allow carry-on overhead bin usage on some aircraft configurations, and it boards last, so overhead space is often gone by the time you board. If you need a carry-on in the overhead bin plus a checked bag, Blue Basic is likely not the cheaper choice once you add the carry-on fee.
Blue Extra is worth noting because it often confuses travelers. Despite the premium-sounding name, Blue Extra provides no free checked bags on domestic routes. Its benefits are focused on seat selection flexibility and same-day changes, not luggage.
If you need one checked bag, the relevant question is whether paying more for a Blue Plus ticket is cheaper than buying a bag on a Blue or Blue Basic fare.
The math is straightforward. JetBlue charges $39 to $49 for the first bag depending on timing and season. If the fare difference between Blue and Blue Plus on your route is less than that, buy the Blue Plus ticket. You get the bag included, plus seat selection and change flexibility that Blue Basic does not provide.
The caveat is that fare differences between Blue and Blue Plus vary widely by route and date. On popular routes during peak periods, Blue Plus can cost significantly more than Blue. Check both fares when you search. If the upgrade is within $15 to $20 of the bag fee, Blue Plus is the better value. If it is $60 more, pay the bag fee separately and take the Blue or Blue Basic fare.
For two checked bags, Blue Plus only covers the first. The second bag costs $59 off-peak whether you are on Blue or Blue Plus. No standard JetBlue fare covers both bags on domestic routes except Mint.
JetBlue’s TrueBlue Mosaic loyalty program has four tiers, and the bag benefit differs by level.
| Mosaic tier | 1st checked bag | 2nd checked bag |
|---|---|---|
| Mosaic 1 | Free | $59 off-peak / $69 peak |
| Mosaic 2, 3, or 4 | Free | Free |
Mosaic 1 gives you the same first-bag waiver as a Blue Plus ticket, but it does not extend to companions on your reservation. If you are Mosaic 1 and traveling with a partner who also needs a bag, they pay the standard fee unless they also hold status or have the JetBlue Plus card.
Mosaic 2 through 4 covers both the first and second checked bags for the elite member. Companion coverage does not come with the status itself. The Plus card (covered below) is the way to extend bag benefits to travel companions.
To earn Mosaic status, JetBlue uses a tile-based system rather than a mileage threshold. Mosaic 1 requires earning 50 tiles in a calendar year, primarily through JetBlue flights and spending on JetBlue co-branded credit cards. For most occasional travelers, the JetBlue Plus card is a faster path to a first-bag waiver than earning Mosaic status from scratch.
The JetBlue Plus card and the JetBlue Premier card each include a first-bag waiver that extends to the cardholder and up to three companions traveling on the same reservation, as of July 2026. The JetBlue Business card carries the same benefit.
The companion coverage is the standout detail. A family of four can each check one bag at no cost if the primary cardholder is on the booking. At $39 to $49 per bag, that is a potential saving of $117 to $147 per direction for the companions alone, before counting the cardholder’s own bag.
The benefit applies only on JetBlue-operated flights. Code-share legs operated by another carrier do not qualify. If your itinerary includes a JetBlue-operated leg and a partner-operated leg, the waiver covers only the JetBlue portion. Verify which carrier operates each segment when you book.
The JetBlue Plus card carries a $99 annual fee. If you fly JetBlue round trip even once per year and check a bag, the math usually works out. One round trip with one checked bag costs $78 to $98 in bag fees at the standard prepaid rates, coming close to the full annual fee before counting points earnings, the $100 annual statement credit for JetBlue purchases, and other card perks.
A standard JetBlue checked bag is one that weighs up to 50 pounds and measures up to 62 linear inches (length plus width plus height), as of July 2026.
Go over either limit and JetBlue adds a flat fee on top of your checked bag fee.
| Situation | Additional fee |
|---|---|
| Overweight: 51 to 99 lbs | $150 |
| Oversize: 63 to 80 linear inches | $150 |
| Bag that is both overweight and oversize | Both fees stack ($300 total surcharge) |
| Bag over 99 lbs or over 80 linear inches | Not accepted as checked baggage |
Unlike some airlines that charge a lower fee for the 51-to-70-pound range and a higher fee above that, JetBlue uses a flat $150 for any overweight bag from 51 to 99 pounds. A 52-pound bag and an 85-pound bag both trigger the same $150 charge on top of the standard fee. If your bag is right at the limit, pull something out.
Mint passengers are the exception. Mint allows bags up to 70 pounds at no overweight charge, so both included bags can go to 70 pounds before the overweight fee applies.
The 62-linear-inch rule catches travelers with large hardshell suitcases. A 30-inch checked bag typically measures around 63 to 67 linear inches including wheels and handles. Check your bag’s manufacturer spec against the linear-inch total, not just the height label.
Active U.S. military traveling on official orders receive up to five free checked bags at up to 70 pounds each. Military members on personal travel receive up to two free checked bags at the standard 50-pound limit. These allowances apply to JetBlue-operated flights only, and valid military orders or ID are required at check-in.
JetBlue’s transatlantic flights (primarily to London and Amsterdam) use a separate fee structure. On those routes, Blue Basic pays $75 off-peak or $85 peak for the first bag. Blue, Blue Plus, and Blue Extra fares each include one free first checked bag on transatlantic routes. The second bag on any fare is $109 off-peak or $119 peak on transatlantic routes.
If you are flying domestically on JetBlue and then connecting to a transatlantic leg on a separate ticket, the domestic fees apply to the domestic portion and the transatlantic fees apply separately. Buying a through-itinerary on a single JetBlue booking generally simplifies this.
JetBlue’s off-peak first-bag fee of $39 sits lower than American Airlines ($50) and United Airlines ($40 online), though American and United both price their bags without the peak/off-peak divide that JetBlue applies. During JetBlue peak periods, the first-bag fee rises to $49, bringing it into the same range as American’s standard rate.
Southwest still includes two free checked bags on every fare, which no other major US carrier matches as of July 2026. If you check bags frequently and Southwest serves your route, that remains the straightforward cost comparison to make before booking JetBlue.
Frontier and Spirit (before Spirit’s May 2026 shutdown) have priced carry-ons as paid add-ons, which JetBlue does not. JetBlue includes carry-on bin access on all fares except Blue Basic on certain aircraft, so the apples-to-apples comparison for a traveler with only a carry-on is JetBlue Blue against JetBlue Blue Basic, not JetBlue against budget carriers that charge for overhead bins.
Work through this in order before you buy:
JetBlue’s baggage pricing is more layered than most carriers because of the peak/off-peak split and the late-add fee. The off-peak prepaid rate is competitive. The peak last-minute rate is not. The gap between the cheapest and most expensive way to bring the same bag on JetBlue can be $20 or more per bag, each way, on nothing but timing.

Basic economy costs more than the fare price suggests. Here is what you lose on American, Delta, and United — and when it is worth buying anyway.
Verdict: Basic economy is worth buying only when the price gap is $30 or more, you have no bag beyond a personal item, your plans are locked, and you are not chasing status or miles. For anything else, pay up for main cabin.
