29 Airlines Most Likely to Cancel Your Flight (And How to Avoid Them)

27. Nok Air – Regional Routes, Real Challenges

Thailand-based Nok Air offers budget-friendly regional service, but inconsistent performance and frequent weather disruptions have impacted reliability. With a small fleet and focus on domestic airports with limited infrastructure, delays often turn into outright cancellations—particularly during monsoon season. Customer service is also limited outside major hubs like Bangkok. If flying Nok Air, avoid tight itineraries, prioritize early flights, and opt for refundable tickets or flexible hotel bookings. Keep an eye on local forecasts, as thunderstorms are a frequent spoiler across their routes.
