Delta rules

• Guitars and smaller instruments such as violins or flutes are accepted as your free carry-on item on Delta and Delta Connection flights.
• The case must fit the overhead bin or another approved space, based on room at the time of boarding.
• A full-fare seat can be bought for an instrument up to 165 lb (75 kg). It goes in a seat with a bulkhead or divider in front, in your cabin.
• If an aircraft downgrade removes the instrument's seat, you and the instrument are moved to the next available flight.
• Checked instruments: up to 150 linear inches and 165 lb including the case.
• Delta notes the carry-on policy is not valid for travel to and from the United Kingdom, and codeshare partners may differ.
