Looking to get the shortest flight from here...Rocky Point to Bucharest Romania without a bunch of driving to a distant airport. Is that the background your looking for?
You 2 options within Mexico. Take public bus to Hermosillo Intl. It is a 6 hour bus ride but the buses are actually very nice. I am sure you would fly to Mexico City before leaving for Europe. The other Mexico only option is to take a bus to Mexicali Intl a shorter ride on the bus but a smaller airport too so not too sure about the pricing.
Or Phoenix Sky Harbor or Tucson Intl if travel to the states is possible.
I have seen deals that combine your Bus ticket with your air ticket. Check with the bus line to see who they are affiliated with, thats your best option for Hermosillo departure.
That's what I am beginning to see as the best option. Didn't really want the drive. either way, it's a trip to any airport i see. Be nice when they get international planes here in RP...not holding my breath:notme:
