On Southwest Airlines in 2026, you are permitted to change your designated Companion up to three times per calendar year after your initial designation. This means you can effectively have four different companions over the course of the year (your original choice plus three changes). To change your companion, you must call Southwest or manage it through your online account, but there is an important caveat: you cannot have any active "Companion" reservations booked for your current companion when you make the switch. You must first fly or cancel all existing companion flights before the system will allow you to name a new individual. Once the change is processed, it can take a few days for the new Companion Pass to be issued, though the digital version is usually updated almost instantly in the Southwest app. This flexibility is one of the most loved features of the program, allowing travelers to switch between a spouse, a child, or a friend as their travel needs change throughout the year, provided they stay within the "three-change" limit for that specific cycle.
