Bringing a small musical instrument onto the plane You won’t have to pay extra to bring your instrument on as cabin baggage if it meets the following requirements: The instrument can be stowed safely in a baggage compartment, or under your seat, and There is space for your instrument to be stowed safely at the time that you board. Space for instruments can be allocated on a first come first served basis, so we recommend taking any early or priority boarding options where possible. It’s worth noting that although you will not have to pay extra for having a musical instrument, you will still have to pay any standard fees that the air carrier would usually charge for similar carry-on baggage. Bringing a large musical instrument onto the plane For larger items that do not fit into the stowage areas, an additional seat must be purchased or the instrument travels as cargo. You’re also advised to make it clear when you book your tickets that you’re planning to travel with a large instrument.

If this happens the airline must work with you to find a suitable solution. Travelling with a large musical instrument as checked baggage If your instrument can’t be carried in the cabin, you can bring it as checked baggage, if: The total length, width and height of the instrument, including the case, is 150 inches or smaller – or it meets the size restrictions of the aircraft if they are different The instrument does not weigh more than 165 pounds – or it meets the weight restrictions of the aircraft if they are different The instrument meets the FAA requirements for cargo If your instrument is too large you may be charged an oversize fee, in line with what the airline would charge for regular oversize checked baggage.
