Flying D. - I'd like to get the flights done as quickly as possible. The first day, I think I'd probably fly from Mexico City right to GUA; and check in to the Radisson there that everyone seems to be raving about. Or, even better, just to get 1 more segment done the first day; MEX-SAL-GUA, if possible

Why do my flights on Expedia price out so high? Is there something I'm missing or doing wrong?

I really and truly appreciate all the help.
