I have a trip schedule for June and had not yet purchased my airfare and so I was checking airfare pretty much every week, every other day since December.
It paid off as I had the option of purchasing a round trip for just $300 (1 seat was available at this price) and I could upgrade to extra leg room with $100 points each leg as a Mosaic level. However, they gave me $15K extra bonus points for making Mosaic Level and I applied all my points towards Mint. The Mint round trip was priced at $1300 down from $1700 in December but with the points I paid $650.00 and $50 for trip Insurance so total $700.
I'm set!
