What changes between these airlines
JetBlue peak dates and advance purchase timing can change a checked-bag price. Delta’s published ordinary rows and cardmember benefits use different conditions. Enter the exact travel date and existing benefits on both sides.
| Airline | When it applies | Standard bag limit | Published fee example |
|---|---|---|---|
| JetBlue | Eligible regional fares; peak calendar and purchase time determine the first two bag prices. | 50 lb; 62 linear in | More than 24 hours before departure: off-peak $45/$59; peak $49/$69. |
| Delta Air Lines | Standard U.S. domestic baggage; eligible fare and benefit checks remain necessary. | 50 lb; 62 linear in | $45 first bag, $55 second bag and $200 third bag. |
The examples above may use different routes, fares, or dates. Don’t subtract one from the other as if they were quotes for the same flight. Use the interactive comparison for your own bag, then open both airlines’ booking flows for the final charge.
Compare your own trip
- Find the fare on each ticket and the airline flying each leg.
- Compare the same bag number, weight, and outside size for the same traveler and direction.
- Keep taxes, currency, and purchase timing in view. If either airline needs a booking quote, you don’t have a reliable price difference yet.
