Is it ok to travel to Korea and then fly to Thailand directly from Korea? What are the procedures? How to buy a plane ticket?

If you have signed the certificate, there is no problem at all.

Thailand is a country where visas can be issued on arrival. You can fly from Korea to Thailand without a visa. Where can the customs take a photo visa after disembarking? The cost is a little cheaper than domestic signing. There are not many visas in Phuket, and it will be done soon. )

So you choose a good flight, book a good ticket, you must sign Korea and book a good hotel. Then we can travel.

I used Ctrip to book air tickets and hotels in Chinese mainland, but its international discount is not as high as that of travel agencies, but you can refer to it there.
