Research Goals & Tasks
The study evaluated how efficiently users can find and book hotel rooms via airline websites. Three core tasks were used to expose navigation, search, and internationalization issues:
- 1. Book any room in Los Angeles
- 2. Book a suite at W Boston
- 3. Attempt to book in a non-English language with foreign currency

Research Flow

Key Insights
Delta Airlines
- Ambiguous information architecture led users to the wrong product (e.g., Vacations vs. Stays).
- Search often surfaced partners or irrelevant results instead of the hotel details page.
- No clear path for special requests during checkout.
- Inconsistent language support beyond flight-booking pages; limited currency options.
American Airlines
- Some hotels were missing or surfaced with limited room types.
- Outdated information observed on hotel pages.
- Restricted language options (only a few languages supported).
- Search results didn’t consistently align with user intent.
United Airlines
- Language switching was unreliable and hard to discover.
- Translation errors (e.g., currency labeled under “Location”).
- Price inconsistencies across currencies suggested unclear conversion logic.
Design Recommendations
Delta Airlines
- Clarify IA by separating Vacation, Car Rental, and Hotel Stays into distinct, well-labeled paths.
- Route hotel searches directly to Delta Stays with full property details.
- Add a universal “Special Request” module to checkout flows.
- Extend full i18n and currency visibility across all services.
American Airlines
- Expand hotel inventory and ensure all room types are available.
- Keep hotel data fresh; surface update timestamps where he lpful.
- Broaden language support and streamline language switching.
- Improve result relevance and disambiguation in search.
United Airlines
- Make language/currency controls prominent and persistent across journeys.
- Fix translation taxonomy and review content quality in non-English locales.
- Standardize currency conversion using current exchange rates and disclose logic.
Process & Evidence
All the participants completed the defined tasks while their screens and timings were recorded. Observations were time-stamped and mapped to findings to maintain traceability.
Outcome
The audit produced a prioritized set of UX issues and concrete design actions for each airline site. The next phase would prototype improved navigation labels, a unified language/currency header, and a standardized special-request module, followed by A/B testing on critical flows.
