This will get interesting....
Think about this for a second.
I live in the southwest United States and I fly Delta more often than not. I typically fly on RJ's either out of ATL or through ATL.
Now, SWA comes into town. 737's to everywhere I previously flew on an RJ. And, the frequent flyer awards to a free ticket are easier to attain.
What the eph do you do now if you are RA?
A 100 seat jet is starting to look more important now.
Plus, it is not going to be long that my pilots will be making more and more noise about their pay rates vis a vis SWA's as they see same or smaller a/c operationg out of the same market making signifcantly mo' dough.
