Thailand’s normally reliable domestic and regional air network has been hit by a fresh wave of targeted cancellations, with Thai Airways, Bangkok Airways and several other carriers scrapping a cluster of key flights serving Bangkok, Chiang Mai, Phuket, Udon Thani, Samui and other high-demand routes.

The latest disruptions, reported between January 20 and January 22, 2026, come on top of a series of operational hiccups over recent weeks and have left some passengers isolated on islands, facing missed connections, and scrambling to rearrange itineraries at short notice.

Fresh Cancellations Hit Core Thai Routes

New data compiled from airline movement reports and airport operations logs shows at least five prominent flights in and out of Thailand’s busiest hubs were cancelled over the last 48 to 72 hours, with the impact felt most acutely in Bangkok, Phuket and Samui. Although the total number of cancellations is modest compared with major storm or air-traffic-control events, the importance of the routes involved has amplified the disruption, particularly for travelers relying on tight domestic connections.

At Bangkok’s Suvarnabhumi Airport, Thai Airways has been grappling with scheduling pressures amid wider congestion across Asia. In parallel, Bangkok Airways has once again trimmed its Samui services, cutting key evening departures to the capital after a similar pattern of cancellations earlier in January. Additional adjustments by low cost and regional carriers on routes touching Chiang Mai, Phuket and Udon Thani have added to the sense of uncertainty for passengers attempting to move around the country during the busy cool-season travel period.

The latest irregular operations follow a wider spike in regional flight disruption on January 20, when airlines across Thailand, Japan, China, Malaysia and Hong Kong collectively cancelled hundreds of services and delayed thousands more. That regional shock created knock-on effects for aircraft positioning and crew duty rosters, feeding into the more localized cancellations now being seen on Thai domestic sectors.

Thai Airways: Delays at Bangkok Add to Network Strain

Thai Airways, the national carrier, has not been at the center of the outright cancellations to the same degree as some competitors, but it has been heavily affected by delays and network congestion at Bangkok. Operational data from January 20 indicated more than 50 Thai Airways departures or arrivals at Suvarnabhumi suffered delays as weather, traffic flow restrictions and regional disruptions rippled through schedules in East and Southeast Asia.

These delays have contributed to missed onward connections to domestic points such as Chiang Mai, Phuket and Udon Thani, with some passengers only discovering at the gate that their onward flight had been retimed or consolidated. Travel agents in Bangkok reported passengers bound for the north and northeast arriving from long haul sectors to find limited same day alternatives, forcing overnight stays in the capital or rerouting via Don Mueang on competing carriers.

Internally, Thai Airways has been working through a broader restructuring and fleet renewal program, with additional aircraft due to join the fleet in 2025 and 2026. While those long term moves are intended to increase resilience and provide more slack in the schedule, the current winter period is being managed with relatively tight aircraft utilization. That leaves the airline vulnerable when external shocks occur, especially when they originate at major regional hubs that feed its Bangkok network.

Bangkok Airways Under Scrutiny After Repeated Samui Cuts

Bangkok Airways, which operates a virtual monopoly on many Samui routes and markets itself as a boutique full service airline, has drawn criticism from passengers after another round of cancellations on the Samui to Bangkok corridor. On January 21 and January 22, two evening flights from Ko Samui to Suvarnabhumi, both operated by ATR turboprops, were pulled from the schedule, echoing a similar incident on January 8 when the carrier cancelled two consecutive departures on the same route.

These seemingly isolated cancellations have outsized consequences because alternative options from Samui are limited. Travelers on the island rely heavily on Bangkok Airways to reach the mainland and connect onward to Chiang Mai, Phuket, Udon Thani and international destinations such as Singapore and Hong Kong. When short notice cancellations occur, several dozen passengers can be left effectively stranded, with only a handful of remaining seats on earlier or later services, or a multi leg detour via Surat Thani involving ferry and bus transfers.

Bangkok Airways has generally cited operational reasons for the cancellations, including aircraft rotation issues and crew duty limitations, without indicating any single systemic fault. However, aviation analysts note that the carrier has been managing a busy high season schedule centered on a small fleet of aging ATR 72 turboprops and Airbus narrowbodies. Any unexpected maintenance event or crew shortage can quickly ripple into the flight program on island routes where there is no backup aircraft based overnight.

Island Passengers Feel Isolated as Options Narrow

Among those most severely affected by the recent wave of cancellations are passengers on Thailand’s islands, particularly Samui and Phuket, who often have fewer alternative transport modes than those in mainland cities. When flights to Bangkok or other hubs are cut, travelers may find themselves with limited ferry connections, long overnight bus journeys or expensive last minute tickets on competing airlines that still have seats available.

In Samui’s case, cancellations of late evening flights to Suvarnabhumi have forced some passengers to abandon carefully timed international itineraries. Without a same day onward connection to long haul services, travelers returning to Europe, the Middle East or North America can find their trips extended by 24 hours or more. In several cases reported over the past fortnight, tour operators have had to rebook entire groups onto the next day’s flights, absorbing hotel and meal costs while negotiating with airlines on behalf of their clients.

Phuket, with its larger airport and mix of domestic and international airlines, is somewhat more resilient, yet disruptions there have still caused headaches for those connecting to Chiang Mai, Udon Thani and neighboring countries. When multiple airlines across the region cancel or delay flights on the same day, chairs become scarce on remaining services. Some stranded passengers have resorted to flying intraregional detours via Kuala Lumpur, Singapore or Hong Kong, adding hours and cost to journeys that would normally be completed in a single short hop.

Knock On Effects for Chiang Mai, Udon Thani and Secondary Cities

While the most visible issues have emerged in Bangkok and the island gateways, secondary cities such as Chiang Mai and Udon Thani have also felt the consequences of the disrupted network. As aircraft and crews run late arriving from Bangkok or regional hubs, departures from these cities can be delayed or, in some cases, merged with later flights to consolidate loads. This can look like a cancellation from the traveler’s perspective, even if the airline reports it as a schedule adjustment.

In Chiang Mai, tourism businesses have expressed concern that repeated small scale disruptions make the destination appear less reliable for short getaways from Bangkok or connections onward to neighboring countries. Tour operators say that even a single cancelled or heavily delayed flight can cause visitors to lose a full day of sightseeing in a region where many stays are only two or three nights. That risk may push some travelers to consider alternative hubs for regional side trips, particularly seasoned visitors who have flexibility in their routing.

In Udon Thani, a key gateway to Thailand’s northeast and to cross border travel with Laos, delays and cancellations of Bangkok flights have disrupted both business and family travel. Local officials have noted that although the city still enjoys multiple daily frequencies with the capital, the reliability of those flights is critical for commuters and workers who make regular trips for meetings, medical appointments or onward international travel. Even small disruptions can have outsize economic effects in cities that depend heavily on air links for connectivity.

Regional Context: Asia’s Wider Disruption Wave

The recent Thai cancellations must also be understood against the backdrop of a broader period of turbulence for Asian aviation. On January 20, airports across China, Japan, Thailand, Malaysia and Hong Kong collectively recorded hundreds of cancellations and thousands of delays, grounding or slowing operations for major carriers such as Japan Airlines, Cathay Pacific, China Eastern and AirAsia. Bangkok’s Suvarnabhumi Airport was among the hardest hit in Southeast Asia, logging more than 200 delays and at least a handful of cancellations in a single day.

Such large scale regional disruption hampers aircraft and crew positioning, leading to irregular operations over several days until schedules can be reset. Aircraft arriving late into Bangkok from Tokyo, Shanghai or Kuala Lumpur, for example, may miss their outbound slot window to domestic destinations like Chiang Mai, Phuket or Udon Thani. Airlines then face difficult choices between operating flights late at night, risking crew duty time violations, or cancelling and reaccommodating passengers on later services.

Industry analysts point out that Asia’s rapid post pandemic rebound in demand has often outpaced the rebuilding of airline staffing and the reactivation of parked aircraft. This structural tightness in capacity leaves little headroom to absorb shocks from weather, airspace restrictions or technical issues. Thailand, as a central hub for regional tourism, is particularly exposed to these fluctuations, with relatively small operational problems in neighboring countries sometimes translating into cancelled or rescheduled domestic flights.

How Airlines Are Responding and What Passengers Can Expect

In response to the latest disruptions, airlines operating in Thailand have been deploying standard mitigation measures, including voluntary rebooking onto later flights, waivers of change fees for affected departures, and occasional use of larger aircraft to consolidate passengers from multiple cancelled services. However, the degree of flexibility offered remains uneven across carriers, and in some instances passengers have reported long queues at airport service desks as limited ground staff try to process a surge of rebooking requests.

Thai Airways has sought to prioritize passengers with onward international connections and those traveling on a single ticket itinerary, as those travelers are more exposed to complex knock on effects when a domestic leg is disrupted. Bangkok Airways has indicated in previous incidents that it will reaccommodate affected Samui passengers on the next available flight and, when necessary, facilitate rebooking of missed long haul connections booked through partner airlines or tour operators. Low cost carriers serving Phuket, Chiang Mai and Udon Thani, by contrast, typically offer rebooking to the next available flight or credit vouchers, with compensation rules varying according to fare class and airline policy.

For now, the expectation among industry observers is that the current wave of cancellations will remain sporadic rather than systemic. There is no indication of an immediate safety, regulatory or infrastructure crisis behind the disruptions, and most affected routes continue to see multiple daily flights. Nonetheless, with aircraft and crews running close to their operational limits in peak season, travelers can expect a heightened risk of last minute changes on popular domestic and regional sectors over the coming days.

Practical Guidance for Travelers Heading to Bangkok, Chiang Mai, Phuket, Udon Thani and Samui

Travel specialists advising visitors to Thailand in late January are recommending a few practical steps to reduce the risk and impact of disruption. First, they suggest allowing longer connection windows in Bangkok, particularly when linking a domestic flight to a long haul departure. Rather than scheduling a tight one or two hour connection from Samui or Phuket to an intercontinental flight, passengers are being encouraged to consider morning arrivals for evening long haul departures, or even an overnight in the capital where feasible.

Second, seasoned travelers are increasingly building flexibility into their domestic routing, especially when traveling to islands like Samui. That can include having a backup plan that uses ferry and bus transfers via Surat Thani or Chumphon, or choosing itineraries that allow for re routing through Phuket or Krabi if Samui flights become constrained. While such detours are rarely needed, they can provide peace of mind for those traveling with tight schedules or important commitments on arrival.

Third, experts highlight the importance of monitoring booking details closely and ensuring airlines have up to date contact information. With some carriers favoring app notifications or email alerts over phone calls, passengers who book through third party sites or older email addresses may miss early warnings of schedule changes. Checking flight status regularly in the 24 hours before departure and arriving at the airport with time to spare can help travelers rebook more quickly if a cancellation does occur.

Finally, for routes involving Chiang Mai, Udon Thani and other secondary cities, travelers are being advised to consider booking slightly earlier flights than strictly necessary on days with important onward plans. In an environment where aircraft and crew rostering is tight, the first flights of the day are often least affected by cumulative delays. That simple adjustment can make the difference between a smooth transfer in Bangkok and a missed connection that ripples across an entire trip.
