The free ones are the same ones they charge for, so you're probably better off avoiding them. Prior to that Silvers weren't able select exit rows until check-in at all. So you had to pray someone moved or got upgraded. Now you at least have the option to select the seats. It should be noted that Continental has announced that Economy Plus will be part of the new United: http://www.united.co...67,1314,00.html As it is now, all elites are able to select the E+ seats free of charge on United and as they roll the product out to the Continental planes, I'm sure the story will be the same there too. Me, I'd rather have five more inches of free pitch rather than free pretzels.
