International flights always allow carry-on luggage, but each airline has its own restrictions as to quantity, size and weight. Some international carry-on policies restrict bag weights to 11 lbs. or less, while domestic flights rarely have a weight limit.
You receive your first checked bag on jetBlue flights for free if it adheres to the airlineâs size and weight restrictions. To avoid extra fees, ensure your luggage is no larger than 62 inches and does not weigh more than 50 pounds.
