Short hop on paper; haze season and Bangkok banks still eat buffers.

CNX is only ~3–5 km from the moat, so off-peak Grab/taxi runs often land in 15–25 minutes. Songkran, Loy Krathong, Chinese New Year inbound banks, and weekday Bangkok departure piles still stack Level 2. Feb–Apr burning- season haze can slow ops and make the airside feel worse than the score suggests. Domestic ~90 minutes early is usually enough; international banks want a full ~2.5–3 hours for TDAC QR, immigration, and security.

One building, two wings; no sterile domestic↔international walk.

Facing the building, domestic sits toward the north / right and international toward the south / left on most traveler maps, with a landside indoor connector. Boarding passes and FIDS use Domestic / International labels, not a T1/T2 story like HKT. Same-day domestic→ international connections need landside transfer + CIQ. Screenshot CNX (VTCC) ≠ CEI Chiang Rai.

Coral PP or Bangkok Airways Boutique first; landside sealed water otherwise.

Priority Pass holders usually get better value inside Coral Executive (domestic near Gate 8 or international next to VAT refund) than buying à la carte deep airside — watch the 3-hour stay cap and any premium-alcohol extra-payment flags on the international Coral conditions. Bangkok Airways passengers should use the complimentary Boutique Lounge first. Landside sealed water and snacks before security remain the cheap play with no lounge access.
