Tips for 45 min Connections
Budget extra time because CNX has no formal airside transit process, so most itineraries on separate tickets require a full re-entry through check-in and security.
If arriving internationally, clear immigration and collect bags before heading to the domestic check-in counters, which are a short walk away.
Avoid tight connections during the 15:00-19:00 window when several Bangkok, Chinese, and regional flights cluster and lines build up.
Confirm whether your ticket is a single itinerary through the same airline, as through-checked bags dramatically simplify transfers at this small airport.
Airport facilities are limited, so don't expect lounges or fast-track options beyond a couple of small business lounges near the gates.

Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
Getting Between Concourses
The domestic and international sections sit within the same compact single-story terminal building, connected by a short indoor walkway. International arrivals must clear immigration and customs before reaching the domestic side, and there is no airside transit corridor for connecting passengers, so most travelers must exit and re-enter through check-in and security.
