Availability normally gets re-checked by the airline at the time the actual booking is made. It shouldn't happen often, but there is a potential possibility that the airline will not confirm the booking, even though the availability screen says there is availability. After the booking is confirmed by the airline, availability no longer matters.

I should have added in my original post, that i normally use Amadeus/AUA. Never mind.

the reason i asked is that what shows up on Amadeus doesn't quite reflect what's actually available for sale on a specific routing/date pair. e.g. a SIN-BLR-SIN towards the end of June shows up as :
[KVS Availability Tool - Amadeus: AUA]
Whereas, what's available via singaporeair.com seems to be a full fare Y.

Then the availability you're seeing is accurate. However, there are currently only 2 economy fares published by the SQ, and the EEA fare has some restrictions:

LH Award Booking Classes
 

It appears that LH's award booking classes (O/I/X for F/C/Y) are now showing in Sabre and other GDSs (and are available to KVS Tool users for viewing).

However, this is most likely a glitch, so enjoy it while it lasts ... :)

US-NY POS in Apollo/ITN/CWT / "Processing Error" Message
 

Please note that the US-NY POS setting in Apollo: ITN/CWT is no longer valid. If you have been using that POS, you will need to select one of the other POSs from the list.

Fares in EUR not available through Travelocity.de ?
 

Using KVS 1.5.0 full, when attempting to retrieve Fares in EUR through KVS tool, I receive "Object not found" in my IE or Firefox. Fares in GBP from travelocity.co.uk works fine, same for USD from travelocity.com

Anything I'm doing wrong here ?

Thanks
Chris

Forgot to mention, it was working fine like two weeks ago or so.

Fares in EUR No Longer Available
 

Unfortunately, fares in EUR are no longer available. Fares are still available in CAD, USD, and GBP.

KVS, I'm also having a problem bringing up an itinerary that I have saved on united.com It says it's not found on the website it brings me to.

Suggestions?

Anyone else having the following problem?

For the past 2 days, whenver I click the go button to look for an itin, I get a small popup box saying "CRS Error: Processing Error"

Any ideas how to fix?

Anyone else having trouble using Amadeus/AUA? I am doing flight searches when I know for a fact there are multiple daily services, and it is coming up saying that there are no flights operating that day.
