Yeah, that's it, I've never been East of the Mississippi...since I used to fly corporate all over the planet, I think it's safe to say in addition to flying East of the Mississippi, I've more likely than not been a lot of places you haven't!
What I was trying to point out to you was that RJ's are not soley to blame for delays, in fact it's far from the only problem...In addition to the antiquated FAA equipment, and lack of spending on infrastructure, you might want to open your eyes to the world around you and acknowledge the rapid growth of corporate aviation and the huge increase in numbers from fractional operators that were barely a blip on the radar a decade ago!
(Sigh)....Well, Gr8, I think I said that in the first line of the previous posts that there are other reasons for delays...
Yes, corporate aircraft have increased, however they don't use the major airports as much as the airlines. Go to LGA, ORD, ATL, etc. there are a few corporate aircraft that use the airports, however they are going to be more inclined to use the satellite airports. More accessible, cheaper or no landing fees, etc. etc.
Now, go to LGA, ORD, ATL, etc. and look at the numbers of airline traffic. Look at the numbers of rjs taxiing around....As I believe PCL and others have so astutely stated is that there are other considerations when dealing with the airlines....
How about GATE SPACE. The corporate airplanes get to taxi over to Signature, etc. where it is a lot easier to park, and by virtue of the lack of number of aircraft - ramp or parking space is very rarely an issue.
On the airline side, how many gates are there? Especially, how many can be leased from the airport authority for each airline at each airport? Hmmm....That number also contributes to the overall picture of aircraft allowed at an airport.
Now, most airports(major airports) have limited resources in the way of SPACE. They are physically limited by their locations. A lot of the airports in the US have seen the exploding growth of the cities around them. This limits the runway growth and the gate space growth. There are some physical laws that I am sorry to say that even mighty Congress can't overcome.
Also, stated before, the customer in most cases does NOT want to travel out to a satellite airport for air travel. There are some exceptions, LA. Well, the absolutely insane size and scope of the LA area demand that other airports have commercial traffic. But most other cities people want the convience. In PHX, they have been talking for years about Wilie serving as a feeder for PHX. Its perfect...Three 10,000 foot runways, relatively good space around the airport to develop, etc. But, people don't want to go there. MDW....Where are you going to build any more runways? There is a reason that when SWA went off the runway they went into a ROAD. It is called a CITY. There are already 2 major airports in Chicago. Where are you going to go? Go out to RFD for commercial service? There is some limited service, but it is LIMITED for a reason. The customer doesn't want to travel out to RFD for airline service.
Unless you have the land to build an airport such as DEN did, and even now you are starting to see the town grow out to the airport - building more runways at most of the countries airports is very difficult or impossible - unless you want to displace several thousand homeowners from their homes.
So, yes technology IS a problem. Infrastructure IS a problem. Airspace availability IS a problem. However, when looking at the most of the major airports in the US, they all have physical limitations on the amount of physical growth - runways or gate space.
Again, if the number of rjs using the major airports increase with NO real ability for the airports to accomodate them - physical space issues - then the delays are going to get worse. This issue has come to head in the last few years as - surprise - the number of rjs have increased....
Rjs do have a place in the market. They do serve a purpose..and the airline of today can't survive without them....However, limits need to be placed on them.
