Will F have a spot available for an upgrade at the airport? I will be flying LUX–ZRH–YUL early April, and will be spending a night in ZRH (~17h layover).
I don't know how well F sells in this particular route. Also, what's the usual same-day airport C → F upgrade price like?
Asking because I bought LX C with Aeroplan points, so the same-day cash upgrade at the airport is the only upgrade option for me.
Want to think about if the price is going to be worth it, especially since the prospect of F accessibility is becoming grim starting 2025. (So far, official only in A333, but you know what I mean...)
