This might explain my issue. I have a ticket for my wife and I (on a family membership) BOS-IST-DPS and return. When we booked all were upgradeable but the family membership wasn't working. I got my 4 segments upgraded using expiring vouchers and a few days later after some "feedback" forms, my wife got a call to confirm upgrading her return (DPS-IST-BOS) which was processed using a voucher. We'd still like the outbound segments upgraded but they said the availability was gone once the accounts were updated. I've been checking for months and have had combinations of BOS-IST or IST-DPS available in the app and through the online upgrade portal, but not both at the same time. I've also had some gaps where neither shows.
About 10 days ago we got J class inventory again on BOS-IST and married segment BOS-IST-DPS; however online and call center just says only BOS-IST has upgrade availability.
Using Google flights, I cant find any J fare IST-DPS-IST, and the cheapest Biz is in K through 2026 published schedules. So I guess that means there's no J fare filed on this route? And thus no upgrades?
When I try your suggestion to use multi-city and separate BOS-IST from IST-DPS by a few days I don't even see the nonstop TK flight. It routes IST-KUL-DPS on a partner from KUL.
So is there any other workaround?
If not, how would the "last minute upgrade" logic work here? Should we upgrade one segment now using the voucher or will that prevent us having a shot at getting it done with my one remaining voucher? Does 24 hours apply from scheduled time from the first flight for all or each? Since it's about 10 hours and 10 hour layover, I presume it'd be best to do it at the check in counter at BOS?

One would need access to GDS to know for sure what the segment loads were. My work around, after losing the TK flight info from EF, is to first check the published fares in EF (still possible) to confirm if J is even available for sale on the portion of the route in question; if K is the lowest fare, one then needs to find an alternate route with a published J-fare that includes the desired segment and then try to verify availability of J on the individual segments by forcing a break in potential married segment logic with a long stop-over (ie. using the multi-city search).
