A very easy to use and convenient airport. Arrival was quick and easy to pre-pay for taxi to Guanajuato - 360 pesos was the cost. It's less than 30 minutes to Guanajuato. We arrived at 9:45 for 12:05 departure - much earlier than necessary. No line for CO check-in and no line at security. The snack bar was affordable and there are a couple of decent shops. Even though the airport has jetways they apparently don't go low enough for the regional jets that provide most service so you have to walk outside. Just before boarding there was an additional pat-down security check.
