One important thing every Southwest passenger should understand is the [Southwest Airlines Boarding Process](https://www.airlinesticketoffice.com/blog/southwest-airlines-boarding-process/). Instead of picking a seat ahead of time, you board in a group and choose any open seat once you're on the plane. Your spot in line depends on how early you check in, your ticket type, or if you have loyalty status. Families with young kids or people who need help can board early through preboarding. Knowing how it works can make boarding smoother and less stressful.
