that is high, i'm in the grey zone (between good and way too high) and i'm about 138/78 i was taking medication but it was making me dizzy (dropping my blood pressure too low) which is a no no for flying. i suggest, drop salt, sodium, eat more fruit, get your heart rate up real high at least 3 times a week for 30 minutes, dont smoke, decrease alcohol and stay healthy. i had high blood pressure at 140 on top so 150 seems way too high.
