Can I travel by air if I have high blood pressure?
Many people with stable, controlled hypertension can fly. Poorly controlled pressure, new symptoms or a recent cardiac problem needs assessment before travel. Fitness to fly depends on stability and accompanying conditions, not the diagnosis alone.

Before booking and departure
Discuss travel if treatment has recently changed or readings are unstable. Keep a medicine list and an adequate supply in hand luggage, and ask about dose timing across time zones. Some conditions require medical arrangements with the airline; airline policies are not identical.
During a long flight
Move your legs and walk when safe instead of remaining still throughout the journey. Compression stockings or additional clot prevention depend on individual risk. Do not start aspirin or an anticoagulant simply because you are flying. Continue prescribed treatment as directed.
Symptoms take priority
New chest pain, severe breathlessness or sudden neurological symptoms need emergency assessment rather than waiting for the trip to end. Painful leg swelling, particularly with breathlessness after travel, also needs urgent evaluation. Being cleared for one journey does not replace reassessment when health circumstances change.
