I thought the leased CX planes were temporary measures for 2022 through some of 2023 only? I just booked F DOH-MLE in March 2024. Is it likely it will remain the CX planes with F, or should I expect that they will change planes and downgrade me to J? If I don't want to risk having to change my flight dates due to a no F plane but no J availability in the new plane, should I just change my booking now to J, so I don't run risk of this situation? Or, should I just wait and see?
