Oaxaca to Zihuatanejo

We flew a few years ago- the brief stop in Mex was fine. We flew on Mexicana, which no longer exists. It was a really good service. Now you can buy 1 ticket with Aeromexico, which of course includes the stop in Mex. You can also buy 2 tickets with Interjet (which might be cheaper)- ticket to either Mex or Toluca (very near Mexico city); 1 ticket from there to Oaxaca. Hope this helps you. I have been watching for a good fare from here in Zihua to Oaxaca for a little over a year, and haven't found a good price (for us) yet. We are considering driving- just haven't had the time lately. It's on our list!
