Thank you, I have just done what I can with those flights. A lot of my delays and cancellations are occuring on flights with adequate turn time at 1%. I understand that sometimes this may happen but its happening more than I thought it would. There are 2 aircraft (ones you pointed out) which is difficult to change unless I drop flights and a couple flights due to curfew at my airport but these done seem to be too badly affected. Most of these are at a 4.4 - 8% chance but it is definitely happening more than 8% of the time.
Fair enough. I didn't try and reconstruct the DHC routes. Your plane flying 01/03/05/07 looks good, only a single 55 minute turn between 06 landing and 07 departing. If you look at the route info, you can click on expanded statistics, see it for the last month, and manually count how many delays/cancels from scheduling you've actually had.
My punctuality is at 79% but I will say that 40% of delays and cancellations are due to weather. I only expected an overall delay or cancxellation due to scheduling of around 6%. Do you think i would benefit overall by dropping some flights on some routes to make all flights less than 1%?
You can go to routes-->flight delays, and get an exact breakdown of time lost to scheduling, and also number of cancellations due to scheduling. I have 88 planes, and am running 1% or 1.4% turns on almost all routes, with occasional exceptions. My punctuality is 80.9%, so 19.1% of flights delyed. 17.34% of that delay time is down to scheduling (and 60% weather), which actually comes out to around 3.3% of total flights getting a scheduling delay. I've had 32 of 3050 flights cancelled due to scheduling, right on 1%. That's pretty normal, I think. That the %chance of delay is more like the %chance of a long enough delay to result in cancellations, and the simply delayed are a bit higher.
