What is the purpose of a swap button in an airline booking app?

User Experience Asked by Steven Souter on January 30, 2021

I am new to the community so I appreciate all replies 🙂

First, what is the official terminology for this type of button?

Second, what purpose does it serve in booking a flight?

A flight booking screen with To and From fields, and a highlighted button in between them with an icon of two arrows pointing in opposite directions

One Answer

It's to save the user time from having to re-input values.

I've heard it called a swap button, but that's informal.

This is a common pattern in applications where a trip is being planned (or en route). It allows users to quickly reverse the start and end destinations.

The principle behind it is more important to know: don't make users do more work than they need to.
