I started in Beginner's World to make a test with 7-day scheduling from the very beginning, meaning that I immediately purchased two WB and started scheduling them on a 7d schedule. This means that, until I had enough cash to purchase further aircraft, all my destinations were served 2xw. Cash arrived quickly, I bought more a/c and completed the schedule by having 7 airplanes on it; same went for the next 7 ones and so forth.
I'm wondering if this only worked because we're in Beginner's World, where the conditions are quite favourable in terms of fuel price and airports aren't crowded. In a "full" game world, would starting with a 7d scheduling from day 0 kill an airline because of too many office costs, too few flights per week to build RI, etc.?
I'm looking for answers from experienced (or less experienced) players who have tried it. Thanks.
