Thai Airways Royal Orchid Plus - First class stopover question?

I have done a couple of searches, but can`t find the answer to my question so here it goes:

How does the TG stopover option that they mention in their fare rules work? I am considering Europe-BKK-SYD this winter and would like to spend a couple of weeks in Thailand on the way back from SYD. Would this be allowed, and if so how can it be booked?

TG`s fare rules is (at least to be me) quite unclear:

Travel Class : Royal First class service
Eligibility : These fares apply with capacity limitations determined by the Carriers best judgement
Flight Restriction : Nil
Advance Reservation : Reservation requires for all sectors
Advance Ticketing : Immediately
Stopovers : Free stopover permitted,1 in Bangkok and 2 additional en route in each direction
Surcharges : Not Applicable
Minimum Stay : Nil
Maximum Stay : 1 Year

Any help will be much appreciated ^

One way to add add a stopover is by booking through 'multi-city' search function. Specify date of departure for your second leg and the booking engine will autoprice. However, this doesn't necessarily price it right and most of the time (I am sure this is the case with F ticket as well), these booking engines charge separately for each leg, making the ticket more expensive than what it really should be (with the free stopover).

So, you normally need to call TG (or your TA) to make a booking and specify your stopover. Given that this is unrestricted F fare and that it already states free stopover enroute, you most certainly can have a free stopover within the time limit of your ticket validity (e.g. if your ticket is valid only for 30 days, your stopover should not exceed more than 29 days, etc.).

Hope this helps!

Thanx for the info brahms77 ^

I will try to give TG sales office in Norway a call, but they are notorious at leading customers away from buying tickets at TG.com, so they call sell them instead.

I`ll probably end up calling Bangkok reservation again...

According to the rules you provided, you can do one stopover in BKK, so what you wish to do is OK.
I suggest that you start by trying to book online using multi-city. As you are looking for a discount First class fare, you have to make sure that this fare (say P class) is available n each of the segment you selected. Otherwise, the system will price using F full fare. Because your stopover in BKK induces more airport taxes, the ticket will be slightly more expensive than without stopover.
It will be easier to book by phone, but it is usually more expensive as the internet fares are a bit cheaper than the telephone fares (or same fare bucket).
What I do is use Expertflyer for checking availability in my deisred fare bucket. You can also call TG to construct your itin (as they will see availability) and then tell them that you will think about. Do not ask them to make an optional booking. then you can compare the price they give you with that of the website.
Dont know where you are flying from, but are you sure that TG offers F class?

I have looked at flights from FRA, CDG or LHR, but will most likely fly from FRA because of easy connections from Norway, and that transfer in CDG or LHR can be a bit of a challenge.

When I wrote the OP the price difference between roundtrip and multi-city booking was staggering, but now TG.com gives me the same price for the dates I want so problem solved ^

Thanks for all your tips.
