A quiet pulse. A better arrival.

Most people accept heavy legs and post-flight fatigue as an unavoidable part of long-haul travel. Hours of sitting at altitude, recycled cabin air, and disrupted sleep all take a toll,  and most passengers simply push through it, arriving drained before their trip has even begun.

Firefly changes that. Our clinically validated wearable sits below your knee and uses gentle OnPulse™ stimulation to support circulation throughout your flight,  helping to ease that heavy, sluggish feeling in your legs and helping you feel fresher, lighter, and genuinely ready for what's ahead.

Frequently asked questions

What is Firefly and how does it work?

Firefly is a clinically validated recovery wearable worn behind the knee. It uses OnPulse™ technology, gentle neuromuscular stimulation,  to support circulation and help you feel fresher during and after long periods of sitting. Simply place it, secure it, press the button, and let it work quietly throughout your flight.

When should I use my Firefly device during a flight?

We recommend wearing your Firefly device throughout the majority of your flight, particularly during longer seated periods. The earlier you activate it, the more time it has to support your comfort and help you arrive feeling your best. Most passengers put it on shortly after boarding and wear it until they land.

Is Firefly comfortable to wear on a long-haul flight?

Absolutely. Firefly devices are designed to be worn for extended periods without discomfort. The device sits discreetly behind the knee and the stimulation is gentle enough that most passengers barely notice it while going about their normal in-flight routine,  sleeping, eating, or watching a film.

How is Firefly different from compression socks?

Compression socks apply passive, constant pressure to the legs. Firefly takes a different approach, using active OnPulse™ stimulation to engage the muscles and support circulation more dynamically. It's the same technology trusted by over 1,300 professional sports teams worldwide, now brought to long-haul travel for the first time through the FlyWell programme.

Can I use Firefly beyond the flight?

 Yes,  and we encourage it. Firefly is just as effective on the ground as it is in the air. Whether you're recovering from a long travel day, heading into back-to-back meetings, or preparing for physical activity at your destination, Firefly devices continue to support your recovery whenever you need it most.
