I would just note that ADD tends to frequently change the way they do things in the airport. I have flown through there once every few months on business for the last 2 years. Each time there are new surprises. For example, the Star Gold boarding area near Gate 10 was added sometime last year I believe. Used it once successfully, but on subsequent trips, there have been no guests or staff there, so couldn't rely on getting to your flight when waiting there. I've also had times where I've sat in the premium waiting areas, got bussed to the plane as Star Gold/Business only to find that the whole economy class had already boarded. Not a great experience when you're *G and sitting in economy.

I've also noticed the last few trips that the boarding gates on the lower level no longer have Group 1 boarding areas, meaning they never call business or *G customers to board first. It's typically chaos as everyone in all 5 groups clamors for the queue.

The post should also note that there are no restaurants or stores beyond security, so be prepared to wait at your gate without the option to buy anything to nibble on.

On the whole, I find Ethiopian Airlines to be generally reliable with a good onboard experience, but ADD airport is hectic and frustrating. Sometimes your trip can go off without a hitch, while other times you're stuck in frustrating lines with no one clear on how things are supposed to work that day.
