Travelling during pregnancy?

D • Mama of 2,lost an angel, waiting on number 4💘💓💘 married-blessed💓
I graduated from school- aint got nothing to do rn besides being pregnant. My fianceé has to work tho and next month he will have to fly around a lot. He doesnt want to miss any of my pregnancy time and wants to be with me on every appointment so he suggested me to go with him.
I just dont know if I should do that next month I'll be at like 25-26 weeks and flying from Cali to Miami and England and even England isnt easy and definitly harder for a pregnant woman. 
Should I go tho? Did anyone else fly around nearly every 2 days and is it safe?
