flying to Charlotte, NC
 

I have been a loyal Delta customer for many years but I will be making some trips from WI to CLT in the future months. I noticed huge price differences between American and Delta. I believe CLT is a hub for Am. Is this typical for the pricing or just a fluke at this time? I am not a fan of flying through ORD but for a difference of $200 a ticket I may have to learn to like it. Any advice will be appreciated.

You didn't provide enough information for us to answer. Since we don't what pricing on what route at what time you're talking about, how can know whether it's "normal" or a "fluke"..

From what airport to WI to CLT for what dates are you see what prices in what class (ie, Basic Economy, regular Economy, etc) for each carrier with connections where?

Anyway, yes, CLT is an American hub.

I used Sept 18-Oct 1 for my dates. For a reasonable/desired time choices the Delta fare is $540 and Am. $295. This is for regular economy not the basic. My dates are very flexible. I am not familiar with the Am. web site and I do not know if they have a chart that shows the best/cheapest dates to fly like Delta has? The route is LSE-CLT.

Yes, I know there would be better fares but I prefer the convenience of flying out of LSE.
