JetBlue

JetBlue rules

• An instrument is allowed in place of one carry-on item if it can be stowed under the seat or in an overhead bin.
• The standard carry-on size limits do not apply to instruments. Bin space is first come, first served and is not guaranteed.
• If there is no space, JetBlue gate-checks it and returns it at the gate on arrival.
• JetBlue aircraft have no closets for instruments.
• Larger instruments such as cellos, upright basses and some guitars are accepted in a purchased extra window seat: up to 165 lb, not in an exit row, secured by crew, boarded first and taken off last.
• The crew member securing it decides whether it can be secured safely.
• Checked instruments pay no oversize or overweight fee up to 150 linear inches and 165 lb. Damage is covered only in a hard-sided case.
