Dear Fellow Employee:
Rolling the hub is smoothing out take off and landings throughout the day instead of having banks. It only works at airports with high O&D traffic because of the schedules. For example, at peak times US Airways schedules 92 take off and landings per hour at PHL. Let’s say they do that from 0900 to 1000 and 1000 to 1100 for a total of about 180 flights.
When they roll the hub you could have 60 flights between 0830 and 0930, 60 flights from 0930 to 1030, and then 60 more flights from 1030 to 1130. Therefore, you have 180 flights from 0800 to 1130 and 180 flights from 0900 to 1100.
By spreading out the flow you cut your peak utilization by 50% and dramatically improve your traffic flow with 50% less metal trying to use the same concrete.
The first question that comes to mind is why have they not used this in the past? That’s a good question.
Historically, airlines catered to the business traveler and worked to keep connecting times low, but the business traveler is no longer paying high fares, therefore, you get what you pay for. There will be longer connecting times, but they will not be huge.
The big savings occurs in ground staff and facilities. Instead of unloading and reloading a plane and the going to the break room and watching TV, ground personnel will continuously work flight after flight that will require less people and more productive use of people. There could be ground staff changes in PHL, dependent upon the increase in aircraft utilization.
Management has said the point-to-point flying will increase in the three focus cities, BOS, LGA, DCA, but as Southwest increases their PHL presence I suspect Frank Cortez and Ben Baldanza will increase PHL flights too to further average down unit costs.
The same thing holds true with gates, where the company can lower its lease expense by getting rid of excess gates and using more flights per gate, which is also a more productive of fixed assets.
