I am new to the board, so pardon me if I missed this info in my archive searches. I am flying SF0->EWR on a redeye aboard an Airbus A319 on a full fare ticket. I am a first level Premier. This is a two cabin aircraft, and I was wondering the quality of the first class seats. I am concsidering using 5000 miles to upgrade from coach but not if it will be a marginal experience. Currently there are no seats available, but they might become available. What are the chances that a) seats will become available and b) that I will be able to secure the seat as a full-fare premier? The flight is this monday night. Thanks
