JetBlue Airways Carry-on Luggage Rules
JetBlue Airways's carry-on baggage rules allow each passenger one carry-on bag and one personal item. The maximum size for a JetBlue Airways carry-on bag is 22.0 × 14.0 × 9.0 in (approx 55 × 35 × 22 cm). You are also allowed a personal item, such as a purse, laptop bag, or small backpack, with a size limit of 17.0 × 13.0 × 8.0 in (approx 43 × 33 × 20 cm). This must fit under the seat in front of you.
JetBlue Airways does not specify a weight limit for carry-on luggage or personal items; the carry-on weight limit is --, so you must be able to lift your bags into the overhead bin unassisted. All tickets, including Blue Basic fares, include the standard baggage allowance of one carry-on and one personal item.
