If you do a dummy revenue flight booking at TG's website, it will return fare and scheulde information for flights beyond that date. This confirms that flight information is available past October 24, 2009 except TG is reserving it for its own use for now and does not allow third parties to access and use it.
This practice is silly and makes no sense at all.
Well, it is tough times. TG is currently reviewing some routes (there is another thread on this) and until this is finalised sometime after a late Jan Board meeting then I wouldn't expect any change.
I think that his is less a 'silly practice' and more of a lets get the market and route structure refined exercise. Once this is sorted out, I suspect that forward fares and award availability can be set. Certainly, if fare/award data was available now for Nov 09 to various booking engines, and then changes were imposed, we'd all grizzle about it - remember the impact of the removal of the BKK-JFK?!
I note too that sometimes THAI is quite late loading 'current' fares for the following season (ie the Apr-Oct 09), and that an attempt to book early results in full Y (or C or F) fares at eye-watering prices. Hence, the current stuff you get from the THAI booking engine may well be suspect - and I agree that this, in itself, is somewhat annoying.
