I thought I would look at our return flights for weekend of June 5th and low and behold I booked a First Class return on AA connecting through MIA without an overnight stay for 25,000 miles. Opted for returning on a Friday instead of Sat as Saturday would have been 55,000 miles. Since our stay is for 4 weeks giving up one day didn't hurt for the miles savings. Then I checked this afternoon and now they are 45.000. I know it will probably change but I'm used to that.
