How early is the check-in at Phuket Airport?

Two to three hours. According to the website of poor travel, due to the remote location of Phuket International Airport, it is necessary to reserve 40 minutes to 1 hour on the way to the airport. Phuket International Airport implements strict security measures, and luggage must be checked one by one by X-ray machines before entering the waiting hall. This process is very time-consuming, so leave enough time to check in.
