Some passengers may find it hard to get up and walk around the plane, especially if they are boxed into a window seat on a busy flight.
However there is a clever foot trick using the alphabet which can keep the blood flowing during a flight if unable to stand regularly.
Emirates flight attendant Lauren Guilfoyle spoke to Reader's Digest to explain how the technique worked.

This is important especially on long flights as DVT can be caused by staying inactive for long period of time without doing any leg exercises.
Lauren continued: "[These] circulatory exercises will keep your cheeks looking rosy and make you look more awake when you step off the plane."
Passengers should also make sure to drink lots of water and wear compression socks during long flights to reduce swelling.
