7ER as an FO, international wasn't for me. I couldn't sleep on the plane and never adjusted to the timezone sleep disruption. I did it for several years to check the box, test my tolerance, and see the sights and don't regret it. I learned I am happier doing 1 or 2 leg domestic days with some Caribbean/Mexico/Central American layovers in the winter and mountain or coastal layovers in the summer. I am completely satisfied as an NBA. I enjoy exploring the world on my time off with weeks in a distant time zone to adjust.
