Southwest is very close to implementing a ticketless frequent flier awards so it won't be as easy to sell anonymous awards. You will actually have to go through the broker process just like other airlines.
In addition, they are cancelling the double credits for online bookings as of December 31. Unlike other years, they will NOT be renewing it this year.
I am very interested to see what effect these two changes have on business. I have a number of friends who were fiercly loyal to WN that will no longer be flying them come Jan 1.
