Well at least for a Saturday. We got in around 3 pm last Saturday and the airport was packed. The line to get a visa was huge and wrapped all the way to the entrance of the airport. I'd guess a good hour wait, then the line to present the visa was about half that length. We took the line to the right and bypassed it. But it' seemed like such chaos and people were all over. I am wondering if that is a normal Saturday, or If the airport has outgrown itself. Took us about an hour to get through id say in total. Longer if we hadn't prepaid for our visas. Just thought I'd pass along :). We left yesterday and the immigration line was huge but went by pretty quickly. Security was nearly empty; everyone was in the immigration line.
