Traveling in first trimester?

Hi ladies,
​I recently got my BFP 3 months after a a MMC and I'm beyond thrilled. I still can't believe it happened so fast! 
​That said, it's my fathers 60th birthday next weekend and he's a 3.5 hour flight away. I'll be approx. 6 weeks by then and I'm not sure if I should be traveling. I'm just terrified to take any risks considering my last mc. I'm praying that this pregnancy sticks!!!
​Has anyone had any issues traveling in their first trimester? Can it cause a mc in anyway? Any advice is appreciated!!
