I agree @
ludocdoc, I just like this one for such a low fare/minimal risk in case it doesn't post as special fare using TYP.
There's a longer trip departing tomorrow for 5 nights in Barbados with only one overnight in MIA for $204. Not a MR, but a great price for $575 EQD/5,750K EQM using special fare earning. As I said, there seem to be great last-minute fares consistently pop up on this route. And Barbados can be pretty inexpensive (~70/nt) if you are willing to stay inland.
Anyway I will probably wait until later in the summer when I plan on doing a plat challenge and hopefully there will be better turnaround times then as you mentioned earlier.
