I seriously dont understand why we dont have the +1day feature already. In some bases yes, you can just drop a tiny bit of utilization by not seven day scheduling, but in other bases, its simply not competitive to not seven day. The problems is that without seven day, if you ignore the night all your flights just take off at 5-7 in the Morning so these slots often run out first. it is often impossible to fit three flights a day after these slots are gone and any player flying 50% more flights ( which would still be possible with seven day) per plane will certainly out perform other airline. Therefore a ton of airlines must seven day, and it is so unnecessarily time consuming. It takes be about 5 mins to populate the first day, and 15 mins to fill them all in on short/medium haul seven day, which is a ridiculous waste of time. Takes an hour to schedule 21-28 planes which is kind of ridiculous when a simple easy to code button could chop this time in half.
I feel like the feature is not here simply because Sami need ways to gate large airline from growing too fast, but slow plane acquisition already does this so I Dont understand why we cant have a this quality of life feature.
