I admit I am burning relatively as fast as I am earning (earlier this year I did 120K for an XF SEA-FRA and an XY FRA-BCN) and as soon as I clear 100K, I will aim for XF SEA-EZE and if that falls through, will do SEA-NRT or SEA-SIN in XF to keep my balance low.

That being said, all of my paid travel continues to be on UA. Just booked an F ticket SEA-SAN for July and will be booking SEA-SAT shortly, with a possible SEA-YYZ and SEA-MSY coming, as well.
