Airline App

Case Study


This study was undertaken as part of the course work at the UX Design Institute, Scotland (2019). The goal,  improve airline customer experience by leveraging the first touch point; the booking process.  The exponential growth of mobile and the airline industry's interest in enhancing their digital experience, created a topical and useful framework from which to work.

An assessment of four airline booking apps (United, Delta, Aer Lingus & Eurowings) through usability testing, interviews and online surveys revealed three target areas for redesign and optimization:


Home Screen

Flight Selection

Passenger Info Entry


Competitive Benchmark Analysis

Usability Tests

Customer Interviews & Surveys

Customer Journey Map

Customer Flow

Connecting Flights

Users were greatly swayed by cost, typically selecting the least expensive option, above time, date and comfort.


During testing, the budget flight option often included a layover. On select booking apps, it was unclear which flight had a connection. In fact, users did not realize there was a layover until they began seat selection. They'd completed nearly 90% of the task before realizing they'd need to go back. And by then, their faith in the process was exhausted.


These Insights helped tailor information architecture on this screen, simple adjustments led the way to a cleaner interface with little room for customer doubt.

Cost given priority, large text, isolated from other flight details. 


Each card starts with a direct flight or connecting flight symbol, placed on the left side to facilitate quick scanning and interpretation. These changes eliminated any layover confusion; during the prototype testing phase, users immediately connected the significance of each symbol.
