Can I use the Thai passport control lane at airports if I'm married to a Thai citizen?

If you are married to a Thai citizen, you can usually use the Thai passport control lane at airports. However, responses suggest that whether you can actually access this lane may depend on various factors including being accompanied by your Thai spouse or the discretion of immigration officers at the time. Many users confirm that they have used the lane successfully while traveling with their Thai spouse, but it is not guaranteed every time. It's advisable to enter together to have a higher chance of being allowed through the Thai lane.
