Can someone from USA that travel to Thailand can give me 411 on airport.  Do I need quarantine for 2 weeks as I arrive at the airport or will I just need health check from America before I leave the country?

Despite what you may have heard, there is only a thermal scan at BKK. You might have to fill out a quarantine form stating if you have any C19 symptoms or not. You should check what the airline or government health advice is for Thailand. At worse they will quarantine you for 14 days if you show signs of C19.
