It is possible to fly, take the subway or take a ferry at the age of 75 with high blood pressure. Hypertension is not an absolute contraindication to flying, and 75 year olds with hypertension can fly with confidence if their blood pressure is well controlled. Airplanes do not cause blood pressure to rise, but there is a possibility of nervousness when flying, and nervousness is likely to suddenly aggravate hypertension. If the blood pressure of hypertensive patients is stable, most of the airplane ride is no problem. For safety reasons, you can carry antihypertensive drugs with you, and if you feel dizzy, headache or panic when flying, you can monitor your blood pressure and take antihypertensive drugs if you find that your blood pressure is elevated.
