Is there any consistency yet to the routes flown by the new A350s to snag the newer J seats? I'll be flying back from Madrid and can fly home through Bogota or Mexico City. The 3 daily flights for my date through Bogota show 24 PE (so the old version) and the 3 flights through Mexico City show 28 PE (so the new version), but it sounds like from reading the comments above and elsewhere that it's still a crapshoot. The flight is not until November so that of course adds to the uncertainty.

Anyone have any insight? I'm booking a rewards flight so time is of the essence, otherwise I'd sit tight and give it some time to play out.
