We traveled with our bicycles and contacted Chan Tours right after booking to ask if taking them along was possible. We never received a reply, so we arrived early on departure day to clarify everything in person. We were told that transporting the bikes was possible for an extra fee. We had expected a charge of around 60–130 THB, as commonly mentioned online. However, we were given a “quotation” of 1,400 THB – the same price as our two tickets combined. We tried to negotiate, as this seemed extremely overpriced. The staff claimed that our bicycles would block two seats and therefore reduce the number of passengers. Otherwise, our tickets would be cancelled. In the end, we managed to negotiate the fee down to 1,000 THB, partly because we tried to be understanding. When the bus arrived, the bicycles were simply loaded into the luggage compartment like normal baggage. At that point, the high extra fee was no longer justified. We were told that “this is how it always works,” which we find hard to believe. Apart from this issue, the bus itself was comfortable. The seats reclined well, and we received a small blanket, water, and a snack.

The experience far exceeded expectations: spacious and comfortable seats, air-conditioning, and attentive service from a hostess who provided bottled water, snacks, a hot meal of rice with Thai pork stir-fry, followed later by milk and a refreshing cold face towel. The level of service from Nakhonchaiair Bus was truly impressive.

How far is Khon Kaen from Bangkok?

Buses normally need between 6h and 7h 30m hours to get to Bangkok from Khon Kaen. Note that the travel time is for your reference only and can depend on different factors such as traffic and weather conditions. Heavy rainfalls almost inevitably make the trip longer due to poor visibility or floods. Road and surface repairs which happen quite often, result in detours and longer travel times. Major national holidays, long weekends, or peak season periods may cause delays both in departures and arrivals – plan accordingly to avoid disappointment, especially if you have further connections and a tight schedule.

Of course, they do their job, too, and can be the only option if you hop on/off in the middle of the route.

Travelling by bus essentials

  • If you are planning to travel during the high season, weekends, or national holidays, booking your bus tickets in advance is highly recommended. The demand is at its highest, yet very often, the number of coaches serving the route remains the same. The earlier you reserve your seat, the better. On some routes, you need to secure your ticket more than a month in advance; on others, a couple-of-days advanced booking is enough. During such periods, try to book online beforehand whenever possible, as showing up at the bus station without a ticket may result in many-hours of waiting in the queue or leave you downright stranded.
  • VIP, 1st, Gold, and similar bus tickets are the most expensive option, but they provide a higher level of comfort. Normally the price of such tickets will include wide soft reclining seats, blankets, water and snacks or lunch, and sometimes some toiletries. Upper-class buses travel faster, make fewer stops during the route, and normally provide more spacious seating to their passengers and a better travel experience.
  • Not all buses have an on-board toilet, but generally, for all trips longer than three hours, all operators schedule a bathroom and/or a lunch stop. While operators definitely do their best to keep on-board toilets clean, the smell may be an issue sometimes. For longer trips, booking a seat a bit farther from the toilet may be a good idea. Also, using bathroom stops for your toilet needs is always better than trying to find your balance in an on-board toilet on the run.
  • If you travel by an air-con bus, make sure to pack layers. A hoodie, a warm scarf, or a beanie hat may prove a good idea. Air-conditioning on buses tends to be excessive, and running nose and sore throats abound after even not the longest bus rides.
  • Always use the security belts even if your bus ride attendant or driver does not insist on it. Your safety comes first – for you, for sure. All buses normally are equipped with security belts, but they may be fixed behind your seat. Take time to find the belt and fix it appropriately.
  • To avoid being disturbed by overhead lights, switched on during stops even at night, and too loud music or sound from the on-board entertainment system, have earplugs and a sleeping mask at hand.
  • As a courtesy to other passengers, avoid using strong perfumes or smelly foods. Some foods like cheeses or durians are forbidden to take on-board – check in advance. Alcohol is also prohibited on the majority of buses.
  • Note that if the bus requires refuelling en-route, passengers will be asked to get off the bus. Operators are not allowed to refuel with passengers on board due to safety reasons. Usually, it takes from 5 to 10 minutes and is often combined with a toilet/lunch stop.
  • If not stated otherwise in your tickets, arrive at the bus station 20-30 minutes before departure. It will give you enough time to find the departure platform and check-in. For international trips, you may need more time for check-in and border formalities.
