JQ ADL-NTL would fit
There's a fair bit of slack in JQs ADL schedule, so it may well be ADL-NTL.
For the northern winter, a few things switch around. The daily ADL-OOL will fly OOL-ADL-OOL (currently it flies ADL-OOL-ADL), and the three per week ADL-HBA will fly ADL-HBA-ADL (currently it flies MEL-HBA-ADL-HBA-MEL).
So you have aircraft available in the afternoon four days a week for ADL-NTL on the days the ADL-HBA doesn't run; you also have an aircraft available in the morning four days a week for ADL-NTL when the ADL-MCY doesn't run.
