My next trip to Bangkok and Singapore

I've decided to go Bangkok and Singapore for 7 days from October 17 to 23. Going to Bangkok is a quite long time, since August 2006. I bought a discounted ticket of Thai Airways from Seoul. The price is 599,800 KRW (=about 59,400 Yen) including all taxes, fees and surcharges. Taking with a Thai Airways flight is second time, last time I went to Bangkok and Singapore in August 2006. At that time, I was taking a non-stop flight from Fukuoka to Bangkok. It was a comfortable flight except the seat is too narrow.

 Flights are as follows:

• October 17 OZ131 FUK 11:30 - ICN 13:00/TG635 ICN 17:30 - BKK 22:50 *via Taipei
• October 20 CX713 BKK 11:50 - SIN 15:20
• October 21 CX712 SIN 13:35 - BKK 15:00
• October 22 TG658 BKK 23:10 - ICN 06:35 +1
• October 23 OZ136 ICN 17:55 - FUK 19:20

The first day, I take an Asiana Airlines flight to Seoul, then a Thai Airways flight to Bangkok. The transit time at Incheon is 4 hours and 30 minutes, so it has a plenty of time to change planes. I'm staying in Bangkok for two nights. On October 20, I'm going to Singapore by Cathay Pacific. The price of business class between BKK and SIN is very cheap, it's 12,490 THB (=about 42,300 Yen) for round-trip. I can also take the latest Airbus plane, A350s. I'll stay in Singapore for only one day and return to Bangkok. I'll go back to Seoul on red-eye flight the next day.
