I recently booked a premium economy multi city flight with American. As I was testing bookings, I came up with a flight from MIA to BCN(direct) and returning BCN to FLL. I live in Fort Lauderdale, so flying out of MIA is ok, but I wont fly into MIA unless its absolutely necessary. My return flight has a 2.25 hr connection in CLT. The fare came up at $898 for premium economy. Even though the flight is not until next May, I thought that was a great price so I booked it. About a week later, I tested a dummy booking, and the fair today is $2007 pp. Quite a jump.
