I'm hoping to be able to find a way, most likely by air, to travel to guam at the end of August. The only catch is that I'm not quite certain when I be coming back. It might be around the New Year or maybe next summer...what are my options. I've looked into one-way tickets, round trip tickets, open ended tickets (although couldn't find much there), online vouchers and the cheapest I can come up with is $1650. Is this truly the best case scenario or am I missing something?
