Swollen Legs and Feet After Flying? Here’s How to Prevent It

Whether you’re travelling interstate, heading overseas, or returning home after a long holiday, swollen feet and ankles after flying are incredibly common.

Many people notice that their shoes suddenly feel tight or their ankles disappear by the end of a flight. While this type of swelling is usually temporary, it can be uncomfortable and, in some cases, may indicate an underlying circulation problem.

At The Foot Force Podiatry, we regularly assess patients with lower limb swelling and poor circulation. Here are our top evidence-based tips to keep your legs comfortable and healthy while travelling.

Is Swelling After Flying Normal?

Usually, yes.

Mild swelling affecting both legs after several hours of sitting is common.

However, swelling should never be ignored if it is:

• only in one leg
• sudden
• painful
• associated with redness or warmth
• accompanied by chest pain or shortness of breath.

These symptoms may indicate a deep vein thrombosis (DVT) and require immediate medical attention.

For most healthy people it settles within several hours after landing.

10 Podiatrist Tips to Prevent Leg Swelling During Flights

1. Wear Compression Socks

Graduated compression stockings help improve circulation by gently assisting blood back towards the heart.

Compression stockings can:

• reduce ankle swelling
• decrease leg fatigue
• improve circulation
• reduce the risk of travel-related DVT in appropriate patients.

Your podiatrist can recommend the correct compression level for your needs.

2. Keep Moving Every Hour

One of the best things you can do is simply move.

If safe:

• walk up and down the aisle
• stretch your calves
• stand for several minutes every hour.

Movement activates your calf muscles—the body’s natural “second heart.”

3. Perform Simple Exercises While Sitting

Even if you can’t leave your seat, keep your circulation moving.

Try:

• ankle pumps
• ankle circles
• heel raises
• toe raises
• pointing and flexing your feet
• gently tightening your calf muscles.

Repeat these every 30–60 minutes.

4. Stay Well Hydrated

Aircraft cabins are extremely dry.

Drink water regularly throughout your journey and limit excessive alcohol and caffeine, which can contribute to dehydration.

Good hydration supports healthy circulation.

---

5. Avoid Crossing Your Legs

Crossing your legs places additional pressure on blood vessels and can further slow circulation.

Keep both feet flat on the floor whenever possible.

---

6. Choose Comfortable Footwear

Your feet naturally expand during long flights.

Avoid:

• tight shoes
• narrow footwear
• restrictive socks.

Supportive walking shoes with adequate room are often the most comfortable option.

---

7. Reduce Salt Before Travelling

High sodium intake encourages fluid retention.

For a day or two before travelling, try limiting:

• processed foods
• takeaway meals
• salty snacks
• cured meats.

---

8. Wear Loose Clothing

Tight jeans, restrictive waistbands and tight socks can impair circulation.

Loose, comfortable clothing allows better blood flow.

---

9. Elevate Your Legs Whenever Possible

Before boarding and after landing, spend 15–20 minutes with your legs elevated above heart level if possible.

This encourages fluid to return towards the heart and may reduce swelling.

10. Consider Compression Therapy Before or After Travel

For people who frequently experience swollen legs, intermittent pneumatic compression therapy may help improve circulation, reduce fluid build-up and assist lymphatic drainage.

At The Foot Force Podiatry, we provide pneumatic compression therapy for suitable patients experiencing:

• chronic leg swelling
• venous insufficiency
• lymphoedema
• prolonged standing at work
• travel-related swelling
• tired, heavy legs.

A clinical assessment is performed first to ensure treatment is appropriate and safe.

Frequently Asked Questions

How long should swollen feet last after flying?

Most swelling improves within several hours after walking and moving around. If swelling persists for more than 24–48 hours or is worsening, seek medical advice.

Do compression socks really work?

Yes. Graduated compression stockings have been shown to reduce swelling during prolonged travel and are commonly recommended for people at increased risk of leg swelling.

Is foot swelling after flying dangerous?

Usually not. However, swelling affecting only one leg, especially if associated with pain, redness or warmth, requires urgent medical assessment to exclude a blood clot.

Can a podiatrist help with swollen legs?

Absolutely. Podiatrists assess circulation, biomechanics, footwear and lower limb function. We can recommend compression therapy, appropriate footwear, exercises and referrals when necessary.
