I was wondering if anyone has taken USair to Guatemala?
We have frequent flyer miles and we (I assume) could use them.
We are just starting out... just filling out our paperwork and signing with an agency. BUT... I'm looking into things to keep myself busy as things progress.
We still may have to have an escort since my father who is 78 lives with us and I'm worried about leaving him.
we don't know much about traveling out of the country either since we have never done so before.
I don't hear much about people taking USair so I was wondering.
Also, If we can not go , would we be able to give our flyer miles to our agency to use to cut down a little on cost?
Thanks
