That's correct.
The OP stated this....
"He is currently on a 45 day entry free clearance as a UK resident"
He is not in position to use and form of income/combo method.
Also does not wish to commit 800k to Thai bank.
Also some immigration offices do not accept combo method.
Agent or lost cause.
Same reply I gave the previous bloke.
The airline MAY require proof of onward flight.
There are many report of it not being asked for and MANY where it is required.
Actually pretty amazed that it was not required from KL with AirAsia.
It's usually these short haul flights where low cost airlines require the onward flight.
This comes up in general topics.
Here some threads....

EDIT: Sorry OP just noticed you are talking about FEW personal items.
In that case fly with them as check in luggage.
Think you can pay for a Lot of extra kg
What 90 visa are you referring to.
Non O retirement/marriage?
That is an option.
So is 60 day tourist visa with 30 day extension.
Don't be concerned about not being able to obtain the extension.
No problem with that.
You would not extend "once you arrive".......best to obtain extension with couple of weeks remaining on the 60 day stamp.
Yes 2 visa exempt per calendar year via border crossing visa exempt entry.
He will not save 1900 baht.
The border bounce will be far more expensive and time consuming..
Also depends on his location.
Yes it's an option.
You ran into a clerk on a power trip.
There have been numerous reports of obtaining 30 day extensions at many immigration offices including Jomtien even much earlier than 2 weeks prior.
As I stated earlier certificate of residence is only provided by CW if you have done 90 day reports..
Yes realize that's only one province however many trying to obtain TDL consequently obtain letter from embassy.
As stated earlier....In Bangkok to obtain TDL you require certificate of residence OR "letter" from embassy.
The added kicker at CW is that to obtain a residence certificate you need to have done a 90 day report.
Think is becoming common in many other provinces now.
No time limit required but imo crazy not to spend some time near Bui Vien st.
Ripper joint.
Be aware that you will require onward flight for return flying visa exempt.
OP, I think you will have issues.
You can't start off with "money in bank method and switch to combo method midstream.
Another thing to keep in mind is not all immigration offices accept combination method.
Which immigration office do you use.
Indeed the process from visa exempt entry or tourist visa entry to non O retirement or marriage and subsequent 12 month extension is 100% legit and no need for an agent etc. As pointed out by @Andrew Dwyer above.
Note: non O can also be obtained in nearby consulates (eg Savannakhet) and also in your own country.
If your 90 day reports are Samut Prakan then that is where you apply for extension.
Can't see SP transferring your stamps as they were issued at CW.
As for the TM6 forget about it. No need to have a new one.
