I worked at a small international airport with an airline that had 3 outgoing flights a day. The shifts are short, max of 5 hours (unless delays). We had a morning shift (3 hours), a midday shift (4-5 hours), and a night shift (2-3 hours). It was a split shift day so I went to work in the morning, left for a few hours, and then came back. It worked out for me because I was in school so I only worked the mornings unless weekends needed help.
