Thanks to those who helped and offered suggestions. I think the one person who replied asking why get a test should be kicked and banned from here, as that is not what this group is for. It's for visa advice and I did not ask whether I should test. There are plenty of other groups for COVID debate and I do not care what you think or will be fueling your desire to start a arguement. I have done what I believe is right, and I have read in other Thai forums and groups many unvaccinated people are now travelling, which I personally find slightly concerning. I think we can all agree it's a nasty disease that can kill.
Thank you for very helpful reply. I am in Bangkok. Do you have a link to the site? I found a booking site, but it is showing no appointments left for tomorrow.
I have been wearing a mask like locals, except when eating and drinking and when far away from people when outside., as the heat and humidity here can get a bit much for someone not used to it.
Because out in the open people are less likely to catch it. When you are stuck inside a small metal tube with recycled air for 14 hours with possible elderly and venerable people that you could infect, that is not a good idea. Plus my Travel Insurance covers this, so I just have to pay for food that my girlfriend I am staying with can go out and buy from 7-11 cheaply.
to search your arriving international flight to check to see if the flight has regular arrival delays. Suvarnabhumi only has one terminal and two sections - international and domestic - both are connected to the main terminal with domestic check in and security to the left of the terminal (from the street entrance). However you will need to clear customs and immigration and collect any hold luggage, before then checking into a domestic flight. Most domestic flights have to be checked in 45 minutes before departure and hold luggage will need to be checked. Domestic security is normally quite quick and easy. All domestic airlines fly from the same domestic section of the airport, there is no advantage of one airline over another, although Bangkok Airways does have a very nice free airport lounge with free food and drink that everyone flying with them can use, so if you give yourself more time you can then use that lounge for free food and drink and relaxing. Thai Smile and Bangkok Airways also include 20kg of hold luggage in the ticket price, and Air Asia ticket prices do not work out much difference in price after adding hold luggage.
One thing to also double check is if the price includes checked hold luggage, that the price on Skyscanner includes hold luggage. Many European Airlines now sell tickets with around 8-10kg of hand luggage only for international flights, and then adding luggage cost can make tickets more expensive than most Middle East and Asian airlines that include checked hold luggage (normally 23kg to 25kg) as standard in their lowest price. Also some Thai Airways international flights only give 20kg of checked hold luggage, which can be fine if you travel light or only go for a short time, but may be tight if going for 30-45 days and wanting to bring some extra clothes/souvenirs back.
Providing you are not looking to make any changes, it can work out cheaper. I have nearly always used 3rd party agencies for flights through skyscanner. I had two bookings cancelled, one before the pandemic as the airline changed the first flight arriving after the connecting flight(!) which was refunded quite quickly as a result, and an Emirates flight that was cancelled due to the pandemic, that took a bit longer to get refunded, as the airlines were messing about with slow refunds. Even booking with airlines directly you are not safe. Many people who had flights cancelled with Thai Airways never got a refund after they declared bankruptcy, and are still trying to get refunds from them.
