JetBlue allows one free carry-on bag and one personal item per passenger, both subject to size limits. Checked bag fees depend on your fare—Blue Basic doesn’t include free checked luggage, while Blue Plus and Mint fares do. I once called (844) 734-0813 before my trip, and the agent confirmed my route’s baggage costs and weight limit. Oversized or overweight bags incur additional fees, so weighing at home helps avoid surprises. TrueBlue members and JetBlue credit card holders often receive discounts on checked bags.
