22 of those 30 flights involve travel to or from the New York City area and of those, 16 were to JFK airport.  A little more scrutiny reveals that 15 of the 16 involving JFK were flights operated as commuter flights using regional jets.  One would be tempted to simply associate most of the problem with Comair (Delta’s regional affiliate flying many of those chronically late flights) but if it was just Comair’s operations, they would have fantastically late flights for other city pairs as well. 

 

I’m sure a pattern is revealing itself here.

 

First, airports in the New York City area and JFK Airport in particular cannot accomodate the flights unless it is a perfect day.  Since those airports are subject to severe weather both in the summer and winter, a fair number of those flights simply never take off or arrive on time.  Ever.  If there is one minor disruption at a peak flying hour, schedules for most airlines at those airports are shattered.

 

Second, because those flights are regional jets flown mostly by legacy airline “connector” airlines, they take low priority when it comes to dispatching.  If Delta has 25 mainline aircraft scheduled into the airport and another 20 regional jets, then it will give priority to dispatching those mainline aircraft first for the simple reason that there are more passengers on those airplanes.  Regional jets are carrying generally less than 60 passengers on those aircraft and by letting those aircraft arrive late in favor of mainline airplanes, they disrupt the fewest passengers.

 

However, doesn’t it seem a bit deceptive to have flights scheduled for a route that is 100% late?  Wouldn’t it seem deceptive to schedule flights that cannot arrive at least 60% on time with late being no more than 45 minutes at the worst?  Of course it does.  Airlines ask for and get performance guarantees when they buy aircraft.  A new airplane generally has to be within 2 or 3% of the guarantee or airlines receive performance penalty payments and sometimes negotiate their way out of the purchase contracts.  If Boeing delivered an airplane that was 100% over its fuel burn, they would be out of business.  If they delivered an airplane that was 10% over its fuel burn they would be out of business. 

 

The public puts up with this because it is pretty hard to find out just how reliable a flight is when booking a seat.  It can be done but I just did it on a hypothetical flight from DFW to ORD (Chicago) and it took me more than 12 minutes to check out the statistics on just 3 flights.  If those first 3 revealed themselves to be too late on average, I would have spent more time identifying one that wasn’t too late and that did have a seat at the price I wanted to pay.  Selling services that perform that badly would constitute fraud in many other service sectors. 

 

What if airlines had to publish their dispatch reliability and schedule reliabiilty along with a fare?  It would sure make the consumer approach his purchases differently, wouldn’t it?  After all, how willing are you to pay for a full fare economy seat if you know that the flight you are purchasing it on runs 100% late and by as much as 130 minutes?  You probably wouldn’t buy the ticket at almost any price if you are business traveler because those travelers need some predictability and reliability in their schedules.  Likewise, wouldn’t you be willing to pay an extra $20 or $30 to take a different flight at a similar time that *does* have a good track record?

 

One way to evaluate your prospects for a particular trip is to look at which airlines serve that city pair and what their actual performance is for that route.  FlightStats.Com is a good website for this information but don’t be afraid to insist your business travel agent ensure you are on a flight with good dispatch reliability and on time statistics.  It is cheaper to pay $50 more for a good flight than to risk your entire schedule on a flight that has a 100% chance of making you miss a connection and blow an entire business day. 

 

The greater the transparency in the airline industry, the better the service will be.   If we required a variety of statistics be published by airlines in their flight listings, I would be willing to bet there would be a wholesale change in consumer behavior towards those airlines.  Good for good airlines and bad for bad airlines.  Shouldn’t it always be that way?

 

Update:  I’m told by a frequent flyer who flies Continental most often that Continental *does* publish their performance stats on their website when booking a ticket.  To a degree, that is unsurprising since Continental Airlines is one of the very few airlines that has consistently followed a policy of measuring their performance with very real metrics.  A policy that started with Gordon Bethune and has been continued by Larry Kellner.  Well done.
