Stellar Customer Portal: Testing for Clarity and Confidence

From Uncertainty to Confidence in the Booking Experience

Some customers were struggling to find and book flights through Stellar’s interface—but the “why” wasn’t clear. With limited resources and time, I led a lightweight user testing program to pinpoint the root causes and validate quick design improvements.


Key Improvements

Prototype Testing in Real Scenarios: Wrote scripts to guide participants through realistic booking scenarios and built a working prototype to test proposed solutions.

Result: Identified key moments of friction, including time-setting controls and unclear navigation labels.


Clarified Navigation and Booking Controls: Improved labels, added guidance icons, and designed toggle interactions with animation to increase clarity and responsiveness.

Result: Users better understood options like “arrive by” vs. “depart at” and felt more confident when adjusting settings.


Persistent Context for Confidence: Redesigned the results screen to carry forward key information entered by users, maintaining continuity and reducing decision anxiety.

Result: Increased user confidence and trust in the results they were seeing.


Project Impact

In just a few rounds of testing, we surfaced actionable insights that clarified key booking interactions. The changes made a measurable difference in how users understood and navigated the experience—leading to a more confident and successful booking journey.
