Flying after 34 weeks?

Hi I’m a FTM and my husband and I want to take a baby moon. With the way our schedules are I’ll only be able to take it when I’m 34 weeks. Has anyone flown at around 34 to 35 weeks on a 4 hour flight? We were thinking Mexico or Miami. My doctor cleared me for Miami at 34 weeks but I left a message for him to ask about Mexico. Any advice to a new pregnant mama?
