JetBlue prices a checked bag by when you add it. More than 24 hours before departure, on off-peak dates, the first bag costs $45 and the second $59, each way, within the US, Latin America, the Caribbean and Canada. Within 24 hours of the flight you pay the full charge of the Contract of Carriage: $49 and $69. A third bag costs $200. On peak dates, such as late November and the second half of December, even the advance price rises to $49 and $69. Every fare, including Main Base, the fare once called Blue Basic, includes a carry-on of 22 × 14 × 9 in (56 × 36 × 23 cm) and a personal item. A checked bag must stay within 62 linear in (157 cm) and weigh less than 51 pounds. The fees were read on JetBlue's fee page on October 26, 2026, and the full charges on an archived copy of its Contract of Carriage captured on October 14, 2026.

The 24 hour line
Most US carriers sell a bag at one price or at an online price and an airport price. JetBlue draws its line at 24 hours before departure. Its fee page shows the advance price with the saving already included: on the first bag the saving is four dollars, on the second ten. Miss the deadline and the bag falls back to the charge written in the Contract of Carriage, the June 2026 revision of which sets $49 for the first bag and $69 for the second for tickets bought from March 27, 2026. A third bag costs up to $200 for tickets bought from April 17, 2026.
| Bag, each way | Added more than 24 h ahead, off-peak | Added more than 24 h ahead, peak | Within 24 h of departure |
|---|---|---|---|
| First | $45 | $49 | $49 |
| Second | $59 | $69 | $69 |
| Third and more | $200 | $200 | $200 |
Peak dates cancel most of the advantage. On days such as November 19 to 30 and December 17 to 31, 2026, the advance price for the first bag rises to $49 and the second to $69, the same as the full charge. Families flying around Thanksgiving or the year-end holidays should count on the higher figure whatever they do.
Carry-on and personal item on every fare
JetBlue's flight terms state that all fares include both a carry-on bag and a personal item. That covers Main Base, the fare the website used to call Blue Basic, so the cheapest JetBlue ticket still lets a 22 × 14 × 9 in (56 × 36 × 23 cm) bag ride in the bin. For the personal item, the only dimensions printed are in the paragraph about UK and European flights: 17 × 13 × 8 in (43 × 33 × 20 cm). The domestic paragraph does not repeat them. Aim for that size and the bag fits under the seat on any JetBlue route.
Weight and size: one flat surcharge
Where most airlines climb in two steps, JetBlue uses one figure. A bag of 51 to 70 pounds costs $150 extra, and so does a bag of 71 to 99 pounds. A bag of 63 to 80 linear inches pays the same $150. The Contract of Carriage defines a standard bag as one of up to 62 linear in (157 cm) that weighs less than 51 pounds, so a bag of exactly 51 pounds already pays.
Overweight or oversize: what one checked bag costs extra
American Airlines, each way, on top of the bag fee
$100
| Overweight charge | $100 |
| Oversize charge | $0 |
| Checked bag limit | 50 lb, 62 in |
When a bag is both overweight and oversize, American applies the higher fee only.
Who checks a bag free on JetBlue
The airline's co-branded credit cards, offered in two tiers, include the first checked bag for the cardmember and up to three travelers on the same itinerary, on flights operated by JetBlue only. Mosaic members get the first bag included at level 1 and the first two bags at levels 2 to 4, again for themselves and their travel companions on the same itinerary. A military free-bag policy was not found on the pages read for this site, so check with JetBlue before relying on one.
Does the airline’s co-branded card pay for itself in bag fees?

Before you finish a JetBlue booking
Add bags at booking or at least a day before departure, and note whether your dates fall in a peak period. If one traveler holds the card, put the others on the same itinerary, within the limit of three. Weigh the bags at home and keep each under 51 pounds. If you booked before March 27, 2026, your ticket may still carry the older contract charges.
