How late would you travel?! 3rd trimester

My brother is having a destination wedding in Florida when I will be 33.5 weeks pregnant. OB says its okay to travel on domestic flights up to 36 weeks. Thoughts on how late you’d take a 2.5hr plane ride and be away from home??? Even if safe just due to discomfort and possibility that anything could happen it makes me nervous even though I want to be there for my brother.
