Did that really need a whole tweet thread? The gist is that many airports were built before 9/11/2001 and the added security measures since then prevent optimization of the check-in process. This doesn't take into account why even newer airports are so inefficient. I was recently in BER, which was opened last year, yet it seems just as inefficient as any other airport.
