Spot on. With any decent system you can discriminate between duties on trips and flight numbers to destinations. With 10 bids it is impossible.
This is actually a worse system than SBS which was replaced by the previous system 15 years ago. Every new system has been a step back due to meaningless constraints added to the system. A bid should be your dream month and reflect what you actually want in its entirety and then you get what is available; not the opportunity to bid for 3 Days a month.
Being happy with trips to W Africa because it isn’t actually the worst that can happen is a pretty low bar to aspire to��
