I just booked my plane tickets thru e-z air on the princess website.  Two of the flights I selected had the reference of "some flights may not be in your requested class". My trip shows two of my flights in premium economy on United and it allowed me to pick my seats in premium economy.  I talked with a Princess rep to no avail as to what this exactly means.  Has anyone booked flights thru e-z air and flown their trips and really gotten a premium economy seat with no additional charges ? Any lig
