Innovating customer’s search and browse experience for the future at Delta Air Lines

As one of the biggest commercial air lines in the U.S., Delta serves many customers with different needs. As the innovation design intern, I identified core opportunities in the current search and browse ecosystem in the Fly Delta app and Delta’s website and delivered solutions aligned with the company’s strategic innovation roadmap.

I pitched my proposal near the end of my internship and secured approval from the managing director. My pitch also received positive feedback up to the VP level.

For travelers without a set date or destination in mind, Delta currently offers limited ways to browse their inventory and explore options for their next trip

Current system audit reveals dropoff points and opportunities

Current offerings on Delta dot-com such as “Current Flight Deals,” Flexible Dates calendar, and “Deals and Destinations” are not yet available in FlyDelta and integrated seamlessly into the customer journey.

Losing coversion to external platforms

A significant portion of bookings come from external platforms, even for loyal customers and members.

I just always made flight reservations with online platforms.

Search in the age of AI and personalization

Search interfaces are rapidly evolving in the age of AI. Users use search and natural language interfaces and expect to see the best results for them. How might Delta evolve to meet the needs and expectations of future customers?

CORE VISION

How might we make it easier for customers without a date and/or destination in mind to browse Delta’s inventory and discover their next trip?

Understanding existing tech and data infrastructure

I had 1:1 conversations with tech leads to understand the existing infrastructure. It gave me a solid idea of the input and outputs that are possible with flexible search. I can’t share much due to NDA :)

Affinity mapping of insights from cross-functional leaders (NDA)

Because this started out as a solo passion project, I took many initiatives to speak with relevant project owners to gain crucial information and discuss potential ideas.

Aligning with core user and marketing segments

To make the vision compelling, I aligned my vision with company wide customer segments and articulate the alignment of the solution with their needs and wants. I can’t share any specifics because this contains proprietary information.

Mapping customer intents and establishing a framework for exploring design solutions

Before jumping into ideation, I started by defining the intents and use cases for the new flexible search experience. Using a clearly defined journey map and three different intents, I added structure to subsequent design explorations.

The eigen-use case: Helping customers figure out when and where to travel

Taking a closer look at the customer journey segment and intents, I defined the goal of the search experience: to help customers figure out when and where to travel with flexible search + displays of destination and date information. Below is a simple mapping I used to convey this idea.

Exploring different modes of AI search interfaces to align with strategic roadmap

Starting broad, I explored various entry points to incorporate flexibility & personalization at core nodes in the search journey; these experiments were meant to be broad and to raise questions about my vision

takeaway: starting near-term without losing sight of the future

After presenting initial solutions to stakeholders, I decided to explore near term solutions to provide more clarity on how to actually ship this feature.

Entry point

First, I iterated on the entry point of the new search experience – users encounter a search box that allows them to search without entering a date. The area below the search box is populated with a feed for free exploration.

Creating jumping-off points that help users narrow down their options

Whereas the original flow consisted of a rigid structure going from destination to checkout, a more flexible flow accommodates for various intents by showing various kinds of results

Creating the building blocks for search results using systems thinking and atomic design

My iterations focused on designing these different types of jumping off points at the atomic level:

Dynamic interfaces for different user intents to optimize personalization

Leveraging my mapping of user intent from the research & scoping phase, I defined how atomic elements populate the page depending on the intent. This approach allows the algorithm to respond to specific needs presented by different and diverse types of users.

Introducing the Fare Calendar

The fare calendar is a common feature in other platforms for flexible travelers; I set out to design Delta’s version.

Contextual interface showing different date options depending on user input

The overall strategy is to display compelling, specific, and contextual information about different dates. I also use UX psychology is to surface narrower options that force the user to think about their trip without feeling boxed in by a specific date and destination.

CONCLUSION + TAKEAWAY

Planting the seed for flexible search

While a self-initiated project completed in a short amount of time, Flexible Search and Personalization received positive feedback up to the director level because of how I leveraged storytelling and stakeholder engagement to create compelling value.

Balancing baby steps and far vision

One of the biggest challenges in this project is scoping and pushing for innovation rather than being solely bogged down in short-term fixes. I made sure
