Unless...you plan to book your ticket to Texas for a weekend you have to be in Georgia. Then by all means, purchase the flight insurance.
I made a blunder and purchased my ticket for a time when I have to be at training for my trip to South Africa. It's a bummer, mainly because I had to pay a change fee (did you know they charge $150 to change a flight?!)...and it means I won't be seeing my Tehas friends for a little longer.
Anyway, I will now be visiting Texas at the end of April. It may actually work out better, because I'll be done with most of my semester, so I can truly enjoy the time...without distractions.
