I actually tried the blackberry version of this drink, and I think it is amazing. It has just the right amount of sweetness, and doesn't have all the bad stuff that is in soda! Definitely recommend this.
I wouldn't recommend United. They always overbook way TOO MUCH, and usually my party is forced to be separated. Last year they ruined my spring break. And now that they physically assaulted a paying customer because THEY overbooked, I will definitely never be flying with United again.
