Both legs of this flight went smoothly. Both were just over 2 hours with ample time layover in Miami, Fl. Flight departure was 7AM US EDST and arrival was 11:50 Guatemala (equivalent of US CDST). It was very similar on the return flight - easy peasy. Guatemala City airport is easy to navigate and on the small side. one caution for RDU - I arrived 2 hours early (5 AM) - the lines were horrendous for both the bag check at AA and getting through security - it took between 45 minutes to an hour to get through security alone. This is due to increased Summer travel, additional airlines at RDU and additional flights from the airlines that service RDU. TSA says they will add some additional security lanes but part of the slow down was to allow sniffing dogs to canvass all passengers. Consider TSA precheck if you fly often.
