A saw an earlier post regarding Fare Lock on United. I've got several of these locked for 7 days while I figure things out. These are the times that the $10.99 fee is worth it to me. The only catch is there can't be any non-UA operated flights in the trip to qualify for a fare lock. I fly to NAP quite a bit but I'm going to FCO so I can use the United flights the whole way and have a week to figure out which flights I actually want.
