You do not have to change. Great service.

Call Nakhonchai Air at 045269777 - better still, if possible visit their HO in Warin or office at Ubon Bus Station.

Several VIP buses, including a morning departure. As the last reply said, great service, even give you snacks, drinks, and a meal along the way, all for a few hundred baht.

Thanks for that website, very useful since NCA dropped the English on their site. Actually though, I'm lucky, as I only live a few minutes from Ubon Bus Station, so can make personal visits.

I like the First Class to Bangkok - great value.

See plenty of Ubon-Pattaya buses passing through Sisaket both the ordinary white ones and some that seem fancier never traveled by bus in Thailand so idea if its first class or what!

I believe it is the same bus that comes through Surin, and I have used it. YOu don't change buses and it stops in pattaya near Pattaya Klang. Not a bad bus, I use the Gold class, better seats, more leg room. Not to bad at all.

Cost from Surin was about 500 baht, it took about 7 hrs.

to all replies thanks very much,info duly noted.i have been with nakon chai air once before and yes they are very good.going to ubon next month,never been before so looking forward.
