The comment was not made with you in mind-it was a generalisation.

I don't think we have got the answer to my OP
EK logarithms are an unknown but I am pretty sure Business Saver availability is based on loads/times and routes the same way they make available reward seats? So I check and monitor before I book.

ps Reward seats-When I phoned for BHX/DXB/MCT for early October there was only 1 reward seats available so I booked that and I had to pay Economy Flex for MrsSS and she used miles to upgrade and join me.

​​​​​​While I'm sure there are logarithms at play in EK's calculations their algorithms are much more if a mystery :D

That being said I don't know what more of an answer you desire. Savers come and go at all points in time, sometimes two weeks befreb departure Savers are available, I regularly see them a month out on some routes. In all classes (though less so in F). AS to your question about prrcentper of tickets, the fare rules for Savers do indeed reference capacity restrictions and that EK reserves the right to limit number of pax on one flight that are on Savers. Whether that's a fixed percentage, is different per route or even per day we don't know

"logarithms at play in EK's calculations their algorithms "
Don't you just hate autocorrect.;)
Thanks all

ex SA ticketed pax are lucky in that respect

I'm looking to travel from MCT - LHR in December, I would only buy an Econonmy Flex for this sector - however when looking at one way flights Business Saver shows as being sold out, however on a return flight that exact flight has available saver tickets.

If I booked an Economy flex ticket and then upgraded - should I be able to do so?

You are only seeing it on the return because the published Saver fare is a round-trip fare. One-way fares are not the same or half the round-trip fares. You can buy an Economy Flex and upgrade with cash or miles but the same fares will still apply so you'd probably have to pay the fare difference to J Flex. It'll ultimately cost the same as just buying J Flex now

True, i thank the EK gods everyday. I do have to point out that fares have gone up considerably ex-SA, so maybe not praying hard enough. There is a fine line that you gotta be careful in SA with as even thou there are people with money, that is a small percentage, so with all the airline options there is enough airline/options to meet the demand for those who wish to pay but many do not mind flying Y if it is too punchy for J let alone F.

It is an accepted fact that the difference between Y Saver and Y Flex fares ex SA is so small that anyone (or at least anyone who values his / her tier miles) will certainly book Y Flex. But the same does not apply to J and even less to F: I currently have a J saver booking at close to R10K less than the corresponding J Flex booking would have been. Sure, the return yields 5K fewer tier miles but R10K... And a few months ago I had a (rare) F Saver at something like R20K below the F Flex fare with exactly the same milage accrual (as for some strange but pleasant reason F daver and F flex both book into an A fare bucket). The above are all based on SA to Europe fares.
Of course the extra complication is that there are numerous Y fare buckets, even within the Y Saver and the Y Flex 'range', which makes it all quite complicated to understand.

Am keen to try out the A380 J Product on a flight of over 6 hours. I've only got enough Skywards miles to upgrade from Economy Flex to Business Saver on a flight of around 8hrs e.g DXB-LHR. I don't suppose anyone knows of any routes where one way Business Saver fares are often available? If any..?

Thanks!

leisure routes are a good bet. Probably south east Asia. BKK is generally oversold so EK would want to push up Y pax into the J cabin. India always (often) has upgrades available but are short and I think only BOM and DEL get the A380. DPS maybe, perhaps HAN, CRK, SGN. Not sure that any of those get A380s however

On this - just wanted to confirm that if I was to book a one way Economy Flex ticket, with no Business Saver fare available at the time - does this mean it's unlikely I'd be able to upgrade?

That's virtually impossible to answer. but the further out it is, the better chance you have to upgrade. Use ExpertFlyer to monitor trends
