Travel in my province while pregnant

Sino na po naka experience dito mga sis na sumakay sa Air plane while pregnant at 6.4Months? Sa province po kase ako manganganak, my due is March 4, 2021. Safe po ba sumakay ng plane? total 1hour lang naman ang biyahe. Naka book na kase ako Manila- Laoag City. Any requirements po like travel documents needed? Please help and advise. #1stimemom #advicepls #pregnancy #theasianparentph
