Flying out of Thailand with family on Sunday 12.00 pm, what time do we need to be at airport? I've heard something about 4 hours before, which could be difficult as we live in Hua Hin. We all have Thai passports, if this makes a difference.
TLDR : Answer Summary
For a noon flight from Thailand, arriving at least 3 hours prior is generally advisable, especially when traveling with family. Comments from users highlighted experiences suggesting that arriving 3 to 4 hours early can be beneficial for international flights, considering check-in times and potential queues. Passengers with Thai passports may experience faster processing at immigration.
