Bring a neck pillow and a heavy sweater bc it does get cold. I used the blanket for my legs. Also: get a seat in the aisle.

EFlew with SWISS-May 2024

Difficult finding the international terminal in Chicago and have to take a long bus ride to get there, so you need lots of time. Immigration in Zurich was really slow. I had to skip to the front and still barely made my connection.
