I've travelled before to BKK on a one way ticket, but also had a ticket out booked as well. However no one asked about the return ticket, so how did they know it existed or would it somehow appear on the airlines systems even though I was using different airlines ? Reason for asking is I want to book another one way but as I'm not sure how long I'm staying and so would prefer not to book a return until I'm ready. I'm guessing booking the fully refundable return ticket is probably still the best option. Just checked with Emirates and a Flex Plus ticket states Complimentary Cancellation/ or 300US Cancellation charge if you're a no show. Seems you have to go to Modify My Booking to request the cancellation and then complete an online refund form as well. All this seems a pain and of course have to shell out the 37,565 Baht for the ticket as well.

Haha ... blame it on a sticky finger  Indeed, 1200 THB!

Either a typo or you splurged for the ten person van, haha. 1200 for a normal car.  I take Orange all the time to Pattaya and back.  When I first started using them I'd say maybe 1 trip in 10 was substandard in some way.  Now I haven't had a bad trip for a long time.  Once they sent a subaru that looked like it was ready for street racing.  The sport suspension made it one of my most uncomfortable rides ever.  I told Orange that they cannot do that to me again and maybe that message has got through because I've been upgraded for free twice now.  

I can also vouch for them. Been using Nam's taxi quite a few time, always on time and smooth sailing to/from Pattaya and lower suk/airport.

Just had confirmation back from Nam's, bargain, especially compared to the now even higher AOT prices: The price is 1200 bath all tolls included with sedan L.
