You can request the upgrade exactly 96h before each flight segment.
AC876 shows J9 C9 D0 Z0 R0 Y9 W9
Upgrade chances donīt seem too bad, but I wouldnīt say the upgrade is guaranteed. YYZ-FRA r/t flights often have 20+ E/SEs on the waitlist.
AC857 is showing J9 C8 Z8 D8 Z8 R8 Y8 Q4 V0
Business class cabin seems pretty empty. Iīd say chances of getting an upgrade are excellent, but you can better predict your chances once the 7day window for SEs has opened.
