Here are three options when traveling to Puerto. First is to fly into Puerto airport by way of Mexico City. Depending on the day and your layover time in Mexico City it could be 3 to 8 hours. Some people have chosen to stay the night in Mexico City and will fly out the next morning on Viva Aerobus. Option two is to fly into Oaxaca and spend the night flying out the next morning with Aero Tucan. or there are others like Varias, Interjet and Aeromexico The third and last way is to fly into Huatulco usually arriving in Huatulco around 2:00 PM or 4:00 PM. From Huatulco it is a 2 hour drive into Puerto. I do not recommend when flying into Oaxaca City to driving. the drive takes over 6 hours and it is not a great road.
