Mababa ang matress

Mommy, I think you mean blood pressure (mataas o mababang BP) rather than matress, pero I'll answer both just in case! If it's about LOW blood pressure, flying is generally okay pero you might feel dizzy or faint kaya stay hydrated and move around the cabin, talk to your OB din if you're pregnant or postpartum. If you literally meant the mattress being low (like close to the ground), that shouldn't affect flying safety at all, pero uncomfortable sleeping before the trip might leave you tired for the flight. Either way, best to check with your doctor before flying kung may health concern ka, para sure ka lang and may peace of mind ka!
