You cannot accept that I am right. It kills you. There is NO WAY Delta and NWA would completely leave any of their hubs,
Who said they would? I don't think anyone has said anything about completely pulling out all the flights of ANY hub of either NWA or DAL...
Wake up, and actually add something of substance. Airtran has RECORD loads out of MEM? HUH???? Well, ok then? Can you back that up?
Yup. He's absolutely right. MEM is one of our hottest cities, mainly because of a lack of lower-fare options.
However, your next question is the more important one.
Have they added any new service out of MEM of substance?
No, and there's a big reason why (and a shortcoming of AAI planning IMHO - not necessarily in MEM, just as an overall strategy): AirTran doesn't do point-to-point all that much and, when they do, it's because ATL is a LONG way away to connect.
In the case of MEM, there's flights every 2 1/2 hours or so to ATL where they can connect all over the country (only a 50 minute flight). Why push for more gate space in a city that is paying good yields to go to another city where they can't connect?
Just because we're filling the airplanes doesn't mean we would if we started flying MEM-LAS or MEM-LAX, etc. You start focusing your assets on one small group of fliers in MEM, you start losing money.
Incidentally, having come from the red-tail group and watched several ramp-downs and pull-downs in MEM capacity, you'll understand why it would likely be reduced even further with the DAL route overlap.
I see MEM being barely a focus city for a combined NWA/DAL with ATL so close by. This will also allow yields to come up with reduced flight options which will suck somewhat for pax, but we all know fares and yields need to come up anyway.
CVG is another story and, since I don't know as much about it, I'll save it for someone else to comment.
JFK slots suck. They're overrated, saturated with low-cost options, plagued by delays, and are really only good if your airline has international flow you can feed into. A combined DAL/NWA might be forced to give up a few, but I'm betting money the DOT starts capping flights in and out of JFK to help cope with the increased delay problems of the last 2 years and any forced pull-back in a merger would likely be forcibly left vacant by the DOT.
