vacation runs in early year, yes...mileage runs, eh...
Last year booked PHX-STT for $220 rt for January 2014. 5 days in BVI's for $220 plus positioning, absolutely.
Also booked way in advance was SMF-CLT for $170 for a long weekend with the family in early Feb 2014.
And then Wideroe happened and I had to get at least one ticket on that deal just to say I did it. So, SMF-DUB 3 day weekend for $368 round trip, can't say no to that.
but no immediate turn MRs. work travel (and other possible vacation runs that might crop up) is way too unpredictable for that.
