Now I am on Samui island in Thailand.
My son and his girlfriend bought their airplane tickets to Samui from Bangkok before me.
I waited one day, but the same airplane with them was already full, so I had to take a later one.
Anyway air plane tickets are sometimes interesting.
For this Thailand trip, I was checking tickets between Fukuoka and Bangkok.
Fitst I was planning to leave on Wednesday, but I found out if I leave on Thursday I could buy the ticket about 60000yen ($600) cheaper.
It is only one day different, but the price was so much different.
So of course I decided on the cheaper one.
Another time, going to Chiang Mai from Bangkok, I checked one way ticket after round trip ones somehow.
They had special offer for one way tickets.
It was cheeper than the round trip ticket.
So I bought a one way ticket for both ways…
I think the system is a bit strange…
