my mom, who is 79 has a blood pressure reading from a home machine of: first reading 147/68, 2nd reading 143/66 and 3rd reading 139/46, and just now 125/66. She is due to take a flight at 10am to Puerto Rico. She does take one pill a day for blood pressure. Her blood pressure is "emotionally" driven and she does not like, rather hates to fly, is it safe for her to fly today?
