It's a mix: I got an email from my travel agent with details and my eticket number and original Y class. The Aeroplan website confirmed my 3 upgrades, but I never got any further email confirmation. I was able to go into TK website and select seats for one of my biz class segments but their site is fairly broken and won't let me select seats for the other segments (regardless of cabin).

Is there anything specific I should be looking for?

Note that I'm interested in my particular situation but I tried to ask a generic question to help add value to the community. The generic answer is still useful to post here, even if there's a workaround for me.

ExpertFlyer data is the same as your travel agent sees, it's from the same source.

Seat maps are not an indicator of ticket availability (award/upgrade availability especially) as you can have sold tickets with unassigned seats, among other things.

To add a bit more data here the TK website shows I'm in I-class nows for the segments that properly got upgraded. My remaining economy segment is still Y-class.

Apologies I didn't mean to imply the simplistic approach "hey there are seats in biz class why can't I upgrade to one?!?!?" I instead just meant to address the earlier general comment that it might be filling up (I don't believe it really is). To reiterate the reason I'm curious: I used aeroplan.com to upgrade a Y-Class with miles to biz while EF showed J=4, I=0 on one segment and was unable to perform the same upgrade on the symmetric segment (literally the return leg of the same flight a few days later with the same plane, exact same number of booked seats in a code-by-code comparison).

Unfortunately the flights no longer look the same (which makes sense, since I've taken a few of the J-or-I seats).

My reading agrees with yours. I think the EF sync that shows J=4 right now is a red herring and I likely booked I-class and EF just happened to be incorrectly showing I=0 when in fact it was available.

Or, possibly, might there have been POS differences? A bit of poking around can sometimes illustrate how real those differences can be, if you switch between US and UK POS displays for a particular flight.

Sorry I'm blanking on what "POS" means...?

Point Of Sale.

So, for example, if you're in the UK, you might be shown 4 I class seats; if you're in the US, you might be shown zero; and if you're in Canada, you might be shown 7.

That's an explanation for many of the occasions on which someone says "EF told me there are x seats in y class, but the airline said that there aren't any".

Ah, got it. I'm physically in the US and using the Aeroplan.com website and the EF.com website. The Aeroplan site has a language selector, but no other region selection info. The EF size doesn't have any discernible localization controls. Any suggestions for how to tweak those two?

I'm not involving the (absolutely terrible) Turkish website, or it's prototype "new version" that's also available.

I bought my Y-class tickets via AmEx Travel over the phone, but that's not relevant to my searching here since I'm only referring to the info EF has told me relative to what the Aeroplan site lets me do.

Thanks for the details!

Can't seem to find award info on ET 847 on 7/27. Is there a communication problem with the airline?

No, there isn't any award inventory for any cabin on that flight therefore it isn't returned by the airline.

Trying to find fare information for XL (LAN Ecuador) and not getting any results that match ITA.

Whats the best way to deal with LA (LAN) and all its subsidiaries?

For example, a flight is 2 segments - the first one is XL and the second one is LA (operated by XL) but each leg has different fares available in EF and they dont match so I cant figure out how many available in each bucket and how they combine. I am still able to find the flight available in ITA and I can buy it via LAN and AA but not sure which fare code applies. According to ITA it is D but the LA (XL) leg does not have availability in D. Also the D fare in EF shows something like $3k+ while the D fare in ITA shows $600.

Can anyone help? I find trying to put an itinerary in LA (and subsidiaries) the most difficult.

Did you try ITA tools?
