Can You Take a Musical Instrument as Carry-On? Airline Rules

Traveling with a musical instrument raises a question that has real financial stakes for musicians: can the instrument fly in the cabin, or must it go in the hold where temperature changes, rough handling, and low humidity can damage it? The answer depends on the instrument, the airline, the country, and sometimes the specific flight.

US Rules: The FAA Modernization Act

The United States provides the strongest legal protections for musicians flying domestically. The FAA Modernization and Reform Act of 2012 explicitly requires US airlines to allow passengers to bring small musical instruments into the cabin if:

1. The instrument can be stowed safely in an overhead compartment or under-seat storage
2. Space in the compartment or under-seat space is available when the passenger boards

This is a federal law, not an airline policy, which means US airlines cannot simply refuse to carry your violin or flute as cabin baggage if it fits the available space. However, the law's protections are conditional on space being available — boarding last means you may find no overhead space, even if the law nominally protects you.

The law also addresses buying a seat for an instrument:

• If a passenger purchases an additional seat for an instrument, the airline must allow the instrument to be stored in that seat if it can be done safely
• The instrument must be treated as carry-on at the instrument's original ticket price (or lower)

What the US law does NOT cover:

• International flights where the US leg involves a foreign carrier
• Instruments too large to fit overhead even in a soft case (most full-size acoustic guitars, cellos, basses)
• Instruments that are hazardous for other reasons

EU Rules: No Equivalent Law

The European Union does not have legislation equivalent to the FAA Modernization Act. European airlines set their own policies for musical instruments in the cabin. This means:

• A violin that flies free as carry-on on Lufthansa may require a seat purchase on Ryanair
• Policies can change without notice
• Enforcement varies by staff and gate

Instruments That Typically Fit as Carry-On

These instruments usually fit within standard carry-on or personal item dimensions:

Almost always fits (personal item or carry-on size):

• Flute, piccolo, oboe, clarinet — fit in cases well within carry-on limits
• Ukulele (soprano, concert) — approximately 60×23×8 cm in a hard case
• Recorder
• Harmonica
• Travel guitar (3/4 size) — approximately 90×38×12 cm in a soft gig bag — marginal

Often fits as standard carry-on (case-dependent):

• Violin — standard hard case approximately 75×27×12 cm; fits most overhead bins
• Viola (small/medium) — approximately 80×35×14 cm; fits many overhead bins
• Trumpet — approximately 58×30×15 cm in a standard case
• French horn — approximately 55×45×35 cm; typically fits in overhead on wide-body aircraft
• Alto saxophone — approximately 65×35×20 cm in a soft bag; marginal on some aircraft

Usually too large for overhead — requires seat purchase or checked transport:

• Full-size acoustic guitar (dreadnought) — typically 110×45×16 cm in a case
• Classical guitar — similar to dreadnought
• Cello — far exceeds carry-on dimensions; must buy a seat or check
• Double bass — always checked or freighted

Airline-by-Airline Policies

British Airways

BA permits musical instruments that fit within cabin baggage dimensions (56×45×25 cm) as standard carry-on baggage. Larger instruments that don't fit can be carried as an additional seat purchase (CBBG). Cellos may be carried in the cabin on most BA routes with an advance seat purchase.

Delta Air Lines (USA)

Delta follows FAA requirements on domestic US routes. Instruments fitting within standard carry-on dimensions (56×35×23 cm) are allowed. For larger instruments, Delta offers seat purchases for instruments on most domestic and some international routes. Delta explicitly lists musical instruments as eligible for seat purchase in their booking system.

American Airlines (USA)

American Airlines follows FAA Modernization Act requirements. Instruments are subject to carry-on size limits (56×36×23 cm). American permits purchasing an extra seat for instruments — contact reservations before travel to arrange this, as it cannot always be done online.

United Airlines (USA)

United follows FAA requirements. Standard carry-on dimensions apply (56×35×22 cm). Instruments can be purchased as additional seats on most United routes.

Lufthansa

Lufthansa allows instruments within carry-on limits (55×40×23 cm, 8 kg) as cabin baggage. Larger instruments can be transported with an advance seat purchase on most routes. Contact Lufthansa's special assistance team in advance for anything larger than a violin.

Ryanair

Ryanair does not have a formal musical instrument policy beyond standard baggage rules. An instrument that fits within the cabin bag dimensions (55×40×20 cm, with Priority Boarding) is treated as a cabin bag. There is no seat purchase option for instruments on Ryanair — anything that doesn't fit the standard carry-on limits goes in the hold.

This makes Ryanair unsuitable for traveling with acoustic guitars, cellos, or other large instruments in the cabin.

easyJet

easyJet allows musical instruments within cabin bag dimensions (56×45×25 cm) as standard carry-on. Larger instruments are not permitted in the cabin and must be checked. easyJet does not offer seat purchases for instruments.

Emirates

Emirates allows instruments within cabin baggage dimensions (55×38×20 cm, 7 kg). For larger instruments on long-haul routes, Emirates sometimes accommodates cellos and guitars by request — contact the airline in advance. Policies on seat purchases for instruments vary by route.

Tips for Traveling With Instruments

Book Early and Inform the Airline

Contact the airline when booking to declare you'll be traveling with an instrument. This creates a record and in some cases triggers a confirmation. For seat purchases (CBBG), this must typically be arranged by phone, not online.

Board as Early as Possible

Overhead bin space on popular routes fills quickly. Board as early as your ticket class allows. On budget airlines, Priority Boarding is especially important — if you're boarding with an instrument that needs overhead space, being at the back of the queue is a serious risk.

Use a Gig Bag Instead of a Hard Case for Guitars

For acoustic guitars, a quality padded gig bag (3–5 cm of padding) is more likely to fit in an overhead bin than a rigid hard case. A soft bag for a dreadnought acoustic is approximately 107×43×14 cm — still too large for most standard carry-on bins, but fitting into the overhead bins of some wide-body aircraft when laid flat.

Understand Your Hold Checking Options

If the instrument must go in the hold:

• Use a sturdy flight case with solid foam interior padding
• Loosen strings to reduce tension (reduces neck bow risk from humidity/temperature changes)
• Remove or bridge tuning pegs
• Pack the case in a bag or foam wrap if the case allows
• Declare the instrument as fragile — ask for a fragile tag at check-in

Consider Rental at Destination

For high-value or particularly vulnerable instruments, renting a comparable instrument at your destination and traveling without may be lower risk than transporting through the hold. This works well for pianists (use the venue's instrument), guitarists (many rental shops exist in major cities), and string players.

The Bottom Line

In the US, federal law requires airlines to accommodate small instruments in the cabin when space allows. In Europe, there is no equivalent protection — each airline sets its own rules. Small instruments (violin, flute, ukulele, trumpet) typically fit within carry-on dimensions and can be treated as standard carry-on bags. Full-size acoustic guitars generally need a seat purchase or must be checked. Always contact the airline before travel, board early, and remove valuables from instrument cases if they must go in the hold.
