when all the availability disappears suddenly - does it ever come back?
 

I was trying to book TLV-NYC on IB in July 2015.
There was a ton of availability in business - most days, 5+ seats, multiple flights.
My BA/IB accounts were not syncing, so I had to call BA. I procrastinated, and only got the issue straightened out yesterday.
Today, all the availability is gone. Not just some flights are booked up - no availability in business at all for the months of July and August, where there were oodles of it a few days ago.
So, my question is - does it ever come back?
Or should I start booking other, less convenient routings?

Maybe.

Usually anyone booking almost a yr out will find availabililty in bits and pieces month by month and then week by week and then day by day as your date approaches. You just have to keep looking but with almost a yr to go I would say your chances are excellent to very good as long as you keep searching.;)

that's just it - it didn't disappear in bits and pieces.
Where a week ago, there was availability for nearly every day, now there's nothing at all - not for any day in July or August.
It is extremely unlikely that every award seat has been booked up - suddenly, 11 months ahead. It's more like Iberia just took out these seats.

It may work differently at different airlines. There is no one general answer, and you don't want a general answer. So your post belongs in the Iberia forum (I'm alerting the moderators to move it for you).

If thats the case then I suspect some seats could magically reappear at anytime as the airline computer could be updating info. and reconfigure schedule and seats. With almost 11 months to go, I wouldnt panic this far out;)

It's such a dynamic system, and with so many more miles floating around than 20 years ago it's managed in a very different way. You need to check all the time as stuff comes up and then disappears regularly.

UPDATE: As of this morning, all of the awards are back. Well, almost all - except the 4 on July 20 that are already booked, lest this happens again :)

There's a lot of thinking behind all of this. Or none. It depends on your point of view!
