Tips for Flying With a Broken Arm

Can You Fly With a Broken Arm?

Yes, you can fly with a broken arm. But there are rules, timing matters, and you need to plan ahead. The biggest concern isn't pain or inconvenience. It's swelling. Cabin pressure at altitude is lower than on the ground, and that pressure change can cause tissues under your cast to swell, potentially cutting off circulation.

With the right preparation, flying with a broken arm is straightforward. Without it, you could end up in serious trouble.

The 48-Hour Rule

This is the most important rule to know. If your cast has been on for less than 48 hours, most airlines require it to be split (also called bivalved) along its entire length before you can fly.

Here's why: fresh fractures swell. Altitude makes swelling worse. A full, unsplit cast can't expand with your arm, which creates dangerous pressure that can lead to compartment syndrome, a serious condition where pressure builds in the muscles and damages nerves and blood vessels.

The rules vary by airline and flight length:

• Cast less than 24 hours old: Many airlines won't let you fly at all, or only on short flights (under 2 hours) with a split cast
• Cast 24-48 hours old: Most airlines allow it if the cast is split along its full length
• Cast more than 48 hours old: Generally fine to fly without splitting, as initial swelling has usually subsided

Your doctor can split and rewrap your cast before your flight. They'll cut through the plaster on one or both sides and secure it with an elastic bandage, allowing expansion room while still supporting the fracture.

Get Medical Clearance

Before booking your flight, talk to your doctor. They'll advise whether it's safe to fly based on:

• The type and severity of your fracture
• How recently the injury occurred
• Whether you've had surgery (pins, plates, or screws can also be affected by pressure changes)
• Your overall health and circulation

Some airlines require a fit-to-fly letter from your doctor, especially if your injury is recent. Call your airline before you show up at the airport to find out their specific requirements. Getting a doctor's note is quick and can prevent you from being denied boarding.

Notify Your Airline

Contact your airline at least 48 hours before your flight to let them know about your injury. They can:

• Note your condition in your booking
• Arrange wheelchair assistance or priority boarding
• Assign you a more suitable seat
• Tell you exactly what documentation they need

Most airlines offer free seat changes for medical reasons. You won't have to pay a change fee to get an aisle or bulkhead seat when you have a cast.

Choose the Right Seat

Seat selection depends on which arm is broken:

• Right arm broken: Book a left-side aisle seat so your injured arm is on the inside, away from the aisle where carts and passengers could bump it
• Left arm broken: Book a right-side aisle seat for the same reason
• Bulkhead seats: These offer more room to position your arm comfortably
• Exit rows: You may not be allowed in exit row seats if your cast limits your ability to assist in an emergency

Getting Through Security

TSA handles casts regularly, but expect some extra screening:

• Your cast will likely be swabbed for explosive residue. This is quick and painless.
• You'll go through the metal detector or body scanner normally. Casts themselves don't trigger metal detectors unless there's hardware inside.
• If you have metal hardware (pins, plates, screws), let the TSA agent know before screening. You may get a pat-down of the area.
• Arrive early: Extra screening takes a few minutes, and you'll be moving slower than usual. Give yourself at least an extra 30 minutes.

During the Flight

Comfort and safety during the flight come down to elevation and pain management:

• Keep your arm elevated: This reduces swelling. Prop your arm on a pillow on your lap, or use a folded blanket. Ask the flight attendant for extra pillows.
• Take pain medication on schedule: Don't wait until the pain gets bad. Take your prescribed pain medication before boarding or according to your regular schedule.
• Move your fingers: Regularly wiggle your fingers and bend your wrist (if your cast allows it) to maintain circulation. If your fingers become numb, tingly, cold, or turn blue, alert the flight crew immediately.
• Ice packs: Ask the flight attendant for a bag of ice wrapped in a napkin. Applying it to the cast can help manage swelling.
• Loose clothing: Wear a shirt that fits easily over your cast. Button-downs or zip-ups work better than pullover shirts. Cut a seam on an old shirt sleeve if needed.

Luggage and Logistics

One arm changes everything about airport logistics:

• Pack light: You're operating with one functional arm. A rolling carry-on is easier than a backpack when one arm is in a sling.
• Check your bags: This is not the time to maximize carry-on space. Check everything you can.
• Travel with a companion: If possible, bring someone who can help with bags, opening doors, and managing security
• Request wheelchair assistance: Even if you can walk fine, wheelchair assistance comes with someone who helps with your bags and gets you through the airport faster
• Ask for help: Flight attendants, gate agents, and fellow passengers are generally happy to help you stow overhead luggage

Sling Considerations

If your arm is in a sling, keep it on during the flight for support. You'll need to remove it briefly for security screening. During takeoff and landing, make sure your seatbelt is fastened securely. The sling should be positioned over your seatbelt, not under it.

Frequently Asked Questions

Can I fly the day after I get a cast?

Possibly, but your cast will need to be split along its entire length first. Many airlines require casts less than 48 hours old to be bivalved before flying. Call your airline for their specific policy and get your doctor to split the cast before your flight.

Will my cast set off the metal detector at the airport?

A standard plaster or fiberglass cast won't trigger the metal detector. However, if you have metal hardware inside your arm (pins, plates, or screws), that may set it off. Let TSA know before screening. Your cast will likely be swabbed for explosives residue regardless.

Do I need a doctor's note to fly with a broken arm?

Some airlines require a fit-to-fly letter, especially if your injury is recent. Contact your airline before your flight to ask about their specific requirements. Getting a doctor's note is a quick process and can prevent issues at the gate.

Can I sit in an exit row with a cast?

Usually not. Exit row passengers must be able to assist in an emergency, including opening heavy doors and helping other passengers. A broken arm typically disqualifies you from these seats.

What if my arm swells during the flight?

If you notice increased swelling, numbness, tingling, coldness, or color change in your fingers, elevate your arm and alert the flight crew immediately. These can be signs of compromised circulation, which is a medical emergency. This is why the 48-hour cast rule and cast splitting exist: to prevent this from happening.
