Musical instruments can be checked or carried on, subject to space.
Musical instruments are subject to the same size regulations as any other checked or carry-on item. If the musical instrument is large and you'd like to carry it on, you may need to purchase a seat for the instrument, provided there is availability. The instrument or equipment must be secured in a window seat and cannot be secured in the first row or emergency exit rows.
Musical instruments are conditionally-accepted articles, and JetBlue cannot be responsible for damages.
