No, no there isn’t, unless you exclusively travel to Europe. Well, maybe RN — don’t know and don’t particularly care, as it’s a rare route where I’d consider that a reasonable compromise. (Hawaii to/from California is the only one that comes to mind, and it’s not something I fly often). But PZ space has gotten very difficult to find in advance.

Here is a quick analysis of the data from seats.aero, excluding Europe:

North America to Asia: scattered routes this month, and then one flight in January.
Asia to North America;: scatted flights this month, then two the first week of December, and one flight on Christmas.
North America to Oceania: fairly substantial inventory throughout the schedule, but after January, most of it is HNL-GUM and HNL-MAJ.
Oceania to North America: decent availability through the end of the year, a few flights in January, and three total seats beyond January 31
North America to Africa: there are 18 total flights on the schedule with PZ space.
Africa to North America: there are 13 total flights with PZ space, and they’re all in 2024.
North America to “South America*”: limited availability through the end of the year; scattered seats to GRU through 2025.
”South America” to North America: decent availability through the end of the year, and then a couple of flights in 2025.

* seats.aero seems to define the Caribbean and Central America as “South America,” so a lot of this is stuff like IAD-PUJ.

This is the continuation of a pattern from previous years but it’s gotten increasingly worse. And while Europe might be a sweet spot now, I suspect it’s only time before somebody decides to eliminate PZ space there too.

That’s not to say that you can’t get upgraded with PlusPoints: if you know a route well, you can get a pretty good idea for where you’ll be able to clear. But it’s needlessly stressful and a real disincentive to trying to reach 1K if my natural travel patterns don’t get me there on their own.
