my flight number is LH 9764 today it's a A350 i hope they won't downgrade me again, at least i guess they will move me for free to the 777 ?

Edit: I answer my own question, but i think many article says from 31st of March 2024 to 26th of October 2024 i was thinking it's seasonal, whereas actually the flight continue the next day with a A380 will my dream come true

Edit 2 : Other question: As i'm here, the 1A 1F are booked so i booked 2 A and 2F for me and my partner, i think it's weird that 1A,F are not available 1 year in advance, do you think it's possible they become available ? Second question the 2 and 3rd row does open ? what's best for couple beside 1 and 2 ? is 2 and 3 ok ? otherwise i prefer to seat "next" to my partner thanks for the insight.
