Well, my original question was if scheduling is considered usage, or if the routes have to be actually flown. apparently we're gonna talk about different things.
You just answered it yourself. besides,system tells you exactly and repeatedly when a slot is going to get lost. What gave you the idea it would last two month?
A- I don't appreciate the attitude, which seems like a common theme in your responses.
B- this is what gave me the idea, from the messages the system sends on these slot issues:
You must regularly use the airport slots you have acquired for your routes. Not flying a route for two months (or one month after it has been acquired) will lead to suspension and removal of the slot times in question (aircraft maintenance is excluded).
I never generally buy slots in advance. usually i get these annoyingly repetitive messages when i close an unprofitable or lackluster route and re-use the base slots. I've never even noticed the part in parentheses before as I am used to getting the messages for two months. I only noticed this as the situation is different, explained below in my second reply.
Many threads on this topic.
Basically you should not order any slots unless you have a plane ready to schedule them too, otherwise it can/is considered cheating by slot hogging.
Ready to schedule means regardless of the plane being ordered from the Used or New Plane market - don't buy slots until the plane shows up on your schedule as it is then ready to be scheduled.
General rule of thumb: So to play by the rules you should allow a max of 4 weeks from buying the slot to flying the route.
Keep in mind that it can and does take up to 1 week to fly the routes once the plane is delivered to you e.g. if delivered on a Monday it can take 7 days to actually fly an early Monday AM flight depending on the initial delivery time of day.
PS: I have never seen any rules or any threads where a 2 month time frame was indicated as allowed
PPS: and sorry to say but in this case you should lose the slots as you actually are considered as cheating by buying slots so early
A- No thread on this exact topic - I searched.
B- I had a plane originally when I opened the route. I also re-used local slots from a route that i just closed.
C- The slots that I have an issue with were the slots at the destination airports. they are the acquired slots that are the subject of this thread.
D- An unplanned lease termination caused the original aircraft not to be available. the next available aircraft is the one being delivered soon.
E- I realized the difference of time limits between acquired and currently owned slots. the message from the system indicates two months, which is what i am used to when i switch routes around.
I don't cheat, and I take offense to that accusation.
