In my mind, this is a bit of a grey area. The intention wasn't to block out slots at CDG to restrict others, it was to ensure that, working within the confines of the game structure, you could complete your schedule. Some may say it should be left to luck, others say, do what works.
I agree with JetWest; the game needs to be modified to allow the "7-days/1-click" approach.
It gets grey because, as strictly written, it does forbid the described action.
Having said the above, I feel sorry for saftfrucht in this situation. This is usually the type of thing that should be delt with privately, not aired in public while he defends himself against the board here. Ideally, the admins would have stepped in and pulled this thread and dealt with the issue, then clarified the situation to avoid future repeats.
If Sami comes down on the 'it's wrong' side of the fence (threshold??), then I feel that the game needs to be adjusted. Real life isn't a mad race to secure slots on day 1 (or 10 or whatever), slots are negotiated, traded etc. This is one area of the game where it can't mirror reality exactly, so some creative solution may need to be found.
I agree, slot hogging is wrong. However, players being penalised because the game is missing a previously-requested (and bloody useful) feature that would avoid any (real or perceived) wrongdoing, I also feel is wrong.
