Hey mate. "shall" or "will".......the are very similar. Hard to think of a circumstance where the use of either within a sentence changes much. Important here though we look whether "will" changes the substance of the commitment given to us by Qantas.
Qantas shall seek to remain competitive
or
Qantas will seek to remain competitive
Na that won't harm us either way. They made a commitment. They are bound by law to honour it. In return we had to give them efficiency and that section of the job security clause was run extensively in the MOD case and we were ordered to give them that efficiency.
Just looking at some other flight data. Whilst Qantas were dropping services with loads of 85%+ they were moving metal to less popular routes. Singapore had services added when their original loads were only 78.6%. The corresponding months of now and the same months in the year before the change are shown. This is how you drive inefficiency into an airline business.
