Cairo airport must be the most awkward airport in the world. I have flown through all 3 terminals so I know it quite well. There is no point in referring to the appalling terminal 2 as it is no longer in operation. The quality of staff and security processes are the biggest issues in my opinion. Regarding the staff there seems to be a scam between airport officials and taxi drivers to hand you over to the drivers that will rip you off. If you can prearrange transport you will be able to avoid that. There are 2 members of staff at passport control. The first will look at your passport and put the visa sticker on it and the second one will stamp it. And they both sit side by side. You have to security scan your suitcases before you check-in which causes absolute chaos. The stories are endless about this airport. On the up it is a clean airport modern and spacious with good duty free and good dinning options. And I have to say I have seen some improvements over the last 2 years which shows that Egyptians are making an effort to improve it.
