Hello,
Thank you for your query at DoctorSpring.com
Thanks for writing to us.
I have read your details. Let me give you few recommendations, if you are travelling within 4 weeks post hip surgery by plane.
The factors that raise the risk of blood clots during air travel are long immobilization, dehydration, obesity, being very tall or very short (over 6-foot-2 or shorter than 5-foot-2), use of oral contraceptives and inherited blood disorders, according to the WHO.
The low humidity on planes further increases dehydration risk.
Although staying home is the best way for recent surgery patients to minimize their risk of blood clots, several newly developed prescription blood thinners are available and help reduce the danger of clotting in some patients who insist on going on the travel before the risk has leveled. All blood thinners, however, are powerful medications and should be taken only after your physical examination & you’ve weighed the benefits and risks, better to take only after discussing with your treating doctor.
Asprin can be taken but as such has no well documented role in preventing DVT in post surgery travellers.
Here are some ways to reduce the risk of blood clots:
?Avoid travel for at least a month after surgery, if possible.
?Move as much as possible during the trip. If you’re traveling by plane, bus or train, stand, stretch and walk down the aisles and stretch at least every three to four hours.
?Promote blood circulation by exercising the calf muscles with up-and-down movements of the feet at the ankles.
?Wear compression stockings, which are designed to increase blood flow in the legs.
?During travel, avoid tight clothing and shoes that can impede circulation.
?Stay hydrated by drinking lots of water and avoid alcohol and caffeinated beverages.
I hope my opinion will help you.
Stay happy & healthy,
Thanks

If you take necessary precautions, chances of DVT are quite less; Say around 1 in 10,000 as per literature.
