During results presser I had the opportunity to ask Lavinia Lau (Chief Customer and Commercial Officer) about the 777 retrofit program: she confirmed this would be for 30 x 777-300ERs, and says they'll be doing one per month, which means assuming a mid-2024 start, then that's six done by end of 2024, 18 done by end of 2025, 24 by end of 2026, and entire fleet by mid-2027.
