On the move

Sitting at the airport of Lima on the way from Cusco to Buenos Aires. Until now everything has been so smooth here in Peru, so I was almost surprised about the hassle at the airport in Cusco. For the first time I have experienced more complications on a domstic flight than international. In Cusco there was a huge line for the check-in counter. I was there in good time, but anyway I kind of realised this would not work. Anyhow, I lined up like everyone else.The staff from LAN walking along the line however said there was time. But after half an hour I had only moved a couple of meters and I caught his attention again, sayin hey, time is moving much faster that this line. The all of a sudden he realised he had to do something and sent me off to another line and then I was checked in. But still there was a lot of hassle around the security and boarding. Just, simply messy.
I have also experiences some more hassle att immigration than normally. I never ever am asked question at immigration and normally it is a really fast process. But here, and in Brazil they made extra fuss because I am travelling on a diplomatic passport. I could have travelled on my normal passport, but since I entered Brazil on the diplomatic and will re-enter before I leave I had to travel on the diplomatic.
