Thrombosis Risks Double after 4 Hours Travel.
The chances of developing deep vein thrombosis double after traveling for four hours or more, the World Health Organization (WHO) said on Friday in a study estimating one in 6,000 long-haul passengers is at risk.
"There is an increased risk of venous thromboembolism during travel where the passenger is seated and immobile over four hours, whether in a plane, train, bus or car," said Catherine Le Gales-Camus, WHO assistant Director-General for non-communicable disease, and mental health.
"What causes the risk is immobility," she told a news conference. "The risk is not only true for people flying."

Well I guess we are just not designed to travel sitting still, in a machine.

Just another thought. Could blood thinners, pool the blood quicker? If you carried on travelling seated?
