Delta doesn't send out e-mails. I was checking Orbitz for my June weekend every day in the morning, after lunch, and in the evening. The sale didn't appear on Orbitz until after lunch, I booked it over on Delta's site to save the fee and by the next day it was gone.
But this is about the right time of the month too, if the pattern stays the same. I just checked my records and I purchased that $133 fare on March 18. yesterday was May 14. So maybe *MAYBE* if the pattern holds true, there might be another MSP-MCO sale in July.
I just got a Fare Watcher alert from Travelocity. ATA has fares MSP to MCO - stopping in MDW - for $213 thru October 15th. Sun Country has non stop fares at $233 - which I would definitely consider had I not been about to get the Delta sale. Air Tran also has a sale going on for $220s I think.
Lots more options for MSP fliers, albeit not many non- stops - but hey, if I can save over $100 to make a stop in Atlanta - I'll stop.
