BKK airport, reentry desk still inside immigration where is always was.
Automated exit gates somewhat operating with about 70% success rate. But sadly zero from two Australian e-passports today, sent off to a manual queue.
TLDR : Answer Summary
At Bangkok's Suvarnabhumi Airport, the reentry desk remains within the immigration area as usual. The automated exit gates are currently operational but only at a 70% success rate, leading to some travelers, particularly those with Australian e-passports, being redirected to a manual queue due to failures.
