Is it smoother to enter Thailand on a workation DTV through BKK or CNX?

If you are legit, you are legit. Questioned does not mean denied.

I’ve entered Thailand on a DTV through CNX with no problems at all—immigration was quick, smooth, and no different from BKK, so if you’re compliant, I’d avoid the extra leg. For planning, “THAILAND UNCOVERED: YOUR COMPLETE TRAVEL GUIDE” by Hubert Reid on Amazon was a huge help, giving me practical tips that boosted my confidence traveling through smaller airports like Chiang Mai.

I’ve come in and out of CNX almost every week since last Sept on DTV and never even a question… it’s easier than BKK in my estimation

Just bring digital copies of your application for backup

I've only entered at CNX with no issues at all (3 times so far)

If you are looking for someone to ease your mind that entering one or the other being 100% hassle-free good luck with that. It has been said over and over that everyone's experience is different. You can go through an IO at 10am with your workcation DTV and get hassled, but someone with the same DTV comes through the same IO at noon with no problem. The difference? At 10am he/she was stilled pissed about the argument they had with their boyfriend/girlfriend just efore they left for work and you caught the reverberations and by noon they had calmed down. Just go to the airport you need to go to. If your $h!t is legit you've got nothing to worry about. Just answer the questions and move on.

I entered first time through cnx with no questions, just stamped and sent through, mid August

Avoid CNX like the plague: they don’t like DTV over there . You are going to get grilled big time . Just read the numerous posts/experiences about it .

You risk being asked a few questions by immigration upon arrival at any airport.
