Need inventory information? Ask here
 

I've seen that British Airways forum as a similar post, so let's get one here.
If you want to know the different available classes for a flight, ask here and someone may be able to help you.

Provide flight number, airport code for origin - destination and the date.
Example:
AF10 - CDG-JFK - 1st of Feb 2017 / 01-02-2017

Cool Mirk! Glad to kick off, hope you can help me, i'm trying to find out if there is availability for upgrades to business class (upgrade via FB Miles) on the following flight:

AF188 - CDG-HKG - 5th of June/05-06-2017

thanks in advanced!

AF188 on the 5th of June currently shows wide open J availability:But in order to know if you can upgrade you will have to try on AF website or call them, that I do not think anyone here can tell you.

Since you show availability in X class, it means you show award booking classes and since O is not displayed, then this flight is most likely not upgradable.

I'm afraid that this is really not an indication of anything, I can't remember the last time I've seen O availability on AF/KL, and yet after booking an award ticket it was issued in O.

I suspect that might have to do with the fact that award tickets (and upgrades) are issued in France, and EF/KVS do not show availability with a POS of France.

thnx for the info :)

Another one!
 

Would love some availability advice on this one. Looking to upgrade from V to PE...

AF1643 - GVA-CDG - 3rd of March/03-03-2017
AF688 - CDG-ATL - 3rd of March/03-03-2017

Thanks in advance!

Try to add the airports next time, it makes the research on expertflyer easier :)

Sorry it's been a while since I've used it myself and forgot that you need to enter both.

Supports my theory of it being completely full.

Could anyone check the KL598 CPT-AMS for the 13th of March?

Thank you SDQbound. No luck either way, appreciate you checking!
