My wife and I are going leaving on a rtw next August/September, and we have been checking out flights periodically just to see where they are. We are doing buy as we go, and I just found a flight from St. Louis to Lima, Peru for $378/person including taxes and fees. This is WAY lower than anything I've found by a few hundred dollars. Does this seem like a good deal? Anyone else know any budget sites to check for flights to South America? Does connecting in Colombia make it cheaper, and if so, should we be worried about having to connect in Colombia?
My mind is spinning right now with excitement at the thought of actually booking our first flight. I am going back and forth between complete exhileration and excitement and feeling like I'm going to puke.
Is this a too good to pass up deal? Or should I just be patient?
Thanks in advance.
