MIA international check in advice
Need some advice. Flying Polaris business MIA, HND, GUM, ROR. Flight leaves MIA at 6:15am. Last shuttle leaves hotel at 4:30am, arrives at MIA at 4:45am. Is that enough time to check in, check bags, security (Global Entry and TSA pre-chek)? Or pre-order a taxi for 4:00am or earlier? Thanks for advice.
