By now most of you have seen the September schedules and have asked questions about the pairings and bid lines. Specifically some of you have asked, “What happened??, these are the worst pairings and lines ever”. When I originally sent you an email about the September schedules on July 29, I knew there were going to be struggles for the computer pairing program to meet your expectations and ours.
There are a few things that have caused the situation we are in today from where we were in September 2006 or even last month. The schedule file from Delta every month is different and forces ASA to create new pairing solutions for almost every week of every month. This was the case in September as the first week in September had flying gutted from it due to the Labor Day holiday schedule. Every week in September is different as we are moved in and out of markets, we will fly to some markets on Monday, Wednesday, Friday and Comair (or insert another DCI carrier) will fly on Tuesday, Thursday, Saturday and Sunday is a whole new carrier, we don’t have the frequency in the market like we have had in the past and finally there are markets in September that are a CRJ200 on one day, a CRJ700 at the same time the next day and then either switch to the CRJ200 or an ATR the next day and so on. Delta continues to match aircraft to the marketplace and is doing more day of the week scheduling in order to maximize revenue which is understandable.
We also have had 6000 hours pulled from the schedule in September from what we were flying in August. One of the goals for September was to reduce the number of reduced rest overnights and an overall reduction in the scheduled duty hours in a day. Crew Planning was asked to plan trips at a minimum of 10:30 hours in an outstation if at all possible and reduce scheduled duty days to 12-13 hours. We have pushed too many of you to long duty days and then short overnights. Understand your time at home is important but we also must ease off your long days and short overnights. ATL is a challenging airport and we have taken too many hits with crew delays in the mornings in outstations due to crew rest issues or cancellations due to crews timing out. IROP situations on one day flow down into the next two or three at times due to crew rest issues.
All pairing optimizer programs are programmed to make the most efficient pairings possible. They are built on pure mathematical computations that grind out the best overall solution. We asked AOS to help in September with minimizing the number of reduced rest overnights. The program generated a lot of four day trips since they are the most productive overall. Now I know some of you are not convinced. But think of it like this, the computer is trying to use the least number of crews overall for the month or any given day. For every four day trip created, the overall trip days to be covered in a month are less than if you had more three and two day trips. Meaning for every four day trip that is broken apart, it takes one three day and one two day trip to cover the same amount of flying. I will be happy to explain this more in my recurrent class visits because some of this needs to be white boarded out and also give you the opportunity to challenge me on the concepts. It is easier to explain with diagrams than words. I will also spend time with anyone about this on my Friday visits in the crew lounge. The entire Crew Planning department is in New York this week receiving further training on the system. We plan to spend some time with Delta to see if there are ways to reduce the number of market in/outs we do to stabilize the schedules more. I appreciate your feedback and October will have to be a month that we do better on your schedules.
