Optimising check-in Flow for passengers

AirAsia

Enhancing the flight booking experience by simplifying key journeys and reducing decision friction.

AirAsia is a Malaysian low-cost airline serving over 165 destinations across 25 countries. As the company expanded its platform into a super app, the team identified low adoption of the mobile check-in feature.

The challenge was to redesign the check-in experience so passengers could complete the process quickly and contactlessly through the app.

Challenge

Objective

  • Increase adoption of the mobile check-in feature by creating a seamless, contactless experience.

  • Ensure passengers can retrieve and present their boarding passes digitally without additional airport steps.

  • Redesign the e-boarding pass interface to improve readability and reduce information clutter.

Problem Statement

How might we simplify the mobile check-in journey so passengers can complete the process quickly and confidently without relying on airport counters?

Research Objectives

1. Understand passenger needs, motivations, and pain points related to mobile check-in.

2. Map current check-in behaviours and identify expectations for a mobile-first experience.

3. Investigate why passengers prefer airport counter check-in over the mobile option.

We went to research if our hypothesis was true by looking through reviews, articles, comments and journal articles. We then gathered our findings. 

Journal article 1:

Heuristic Evaluation

We conducted an independent walkthrough of the current flow to rest usability and interface issues, we evaluated them with Heuristic Evaluation

Competitor Analysis

We wanted to focus on 3 aspects in our Analysis:

  • ✅ How is their process of check-in is like?

  • ✅ How are relevant information presented?

  • ✅ What do users think about their app?

What I’d Improve

Deeper research into mobile check-in behaviour
Future work could focus more specifically on how passengers interact with mobile check-in, as most existing research focuses on bookings rather than post-purchase journeys.

Broader participant recruitment
With more resources, expanding participant recruitment beyond our immediate network would provide more diverse user insights.

Stronger connection between research and design
Developing clearer user journeys and ensuring personas directly inform design decisions would strengthen the overall experience.

Simplifying interaction patterns
Reducing reliance on pop-ups and exploring more streamlined interactions could improve the flow of the prototype.
