To sum up all of this....I think we a very close to the schedule being extended. Using the information list above, I would say that SW will extend the schedule no later than February 10th. I say that because it has been extended on a Friday for the past 2 years and the current sale will end on the Thursday, February 9th.
Of course, we are already in that 112-135 day range in which they usually extend the schedule....so, we can't count out this week either.
Hope this helps.....that schedule extension should be coming very soon!
