Your safe arrival at the flight destination unfortunately
does not signal the "all clear". The risk of
traveller's thrombosis leading to pulmonary embolism remains
a threat for a few days thereafter. For example, thrombosis
may have already formed in the deep leg veins during the
flight. Several days can pass before the thrombus or its
fragments migrate to the lungs and trigger pulmonary embolism.
For this reason, flight expert Farrol Kahn recommends
that travellers continue taking acetylsalicylic acid (ASA),
e.g. Aspirin® for two to three days after flying to keep
their blood from clotting.
It is equally advisable to spend time in the days after
the flight (and in general) getting as much exercise as
possible. Continuing with the vein gymnastic exercises
is also a good idea.

If, despite taking preventive measures, you should notice
that one of your calves becomes warm, swollen and has
a blue-red discoloration during the flight or even some
time later, you should consult a doctor as quickly as
possible. These symptoms are unmistakable signs of thrombosis.
If you notice the symptoms of pulmonary embolism (described
here),
you must not delay - this really is a matter of life and
death.
Furthermore, it is strongly recommended that you tell
your doctor that you have recently undergone a long-haul
flight. By doing so, you can reduce the risk of an incorrect
diagnosis. After all, any delay can be crucial in pulmonary
embolism. If the correct treatment is initiated early
enough, you are more than likely to escape relatively
unscathed.
