million+ bookings a year
The focus was on simplicity, scalability and mobile-first as a design principle.
We helped easyjet refine their digital booking experience through user research and testing, making it smoother, more intuitive, and accessible for all passengers.
GAIN Experience partnered with easyjet to enhance the usability and accessibility of their digital booking experience. through in-depth user research, including moderated usability testing and accessibility evaluations, we identified key pain points and opportunities for improvement. our insights informed design refinements that streamlined the booking process, making it more intuitive and inclusive for a diverse range of passengers.
A new responsive website that:
Makes it easy to touch, swipe and click; working brilliantly on any device with mobile first as a design principle
Makes it easier to find and book the right flight and flight options
Delivers an easy, focused and familiar booking flow to a wide and varied audience
Is scalable with components that can be re-used across easyJet.com
Increases bookings and basket value
The work
easyJet initially approached GAIN for a new framework for a series of responsive future facing templates that would allow for flexibility moving forward. From the success of the template framework, easyJet asked GAIN to build a fully responsive prototype for the easyJet booking journey.
GAIN and easyJet aimed for a site that would work from a single codebase using any device with any screen size.
A Collaborative Approach
The project has involved GAIN consultants working collaboratively with the easyJet team, across all areas of the business to drive a user-centred design approach.
Regular participatory design workshops were carried out with key stakeholders from around the organisation to involve them in the design process and to take them on the journey. Personas were also created to aid with the design decisions and participant recruitment.
Usability Testing
Early usability testing and an expert review were performed on the existing site to understand what worked well, what customers valued and where the major problems were. Some of the positive offerings were carried through to be included within the new site.
The team then began working on designing templates. The templates were created as high fidelity clickable wireframes as this helped the development team who were rapidly developing code using an agile approach. Over 75 templates were created, each thoroughly usability tested and iterated upon with close to 20 rounds of testing over 3 years.
During our iterative usability testing, we used a strict task tracking table so we could see across a series of standardised activities whether they were successful over multiple rounds and where changes needed to be made. E.g. something may have been fixed in round 2 of testing but this may have impacted another area so it was important to have this standardised. Usability testing was carried out in the GAIN Studios in London and Oxford with over 150 participants being recruited from personas using the GAIN database.
Optimised Design
Major changes included a restructuring of the user journey to focus on the core products of flights, seat sale and adding checked-in baggage. Prior to the redesign, these add-ons were contained within an ‘extras’ page whereas now they can be presented as full steps within the journey.
Bunnyfoot provided a full visual design for the live site working within easyJet’s brand guidelines and developed a library of over 100 font icons to ensure brand consistency by content creators moving forward.
Ongoing Improvements
The new site was initially launched to a small percentage of traffic to monitor and optimize prior to the full launch to all the markets.
Following rollout we continue to work on an extended programme of deliverables, creating further design and presentation improvements that can be tested, and optimized as part of a programme of ongoing improvement.
What we delivered
Held participatory design workshops
An Expert Review and Usability Testing were performed on the previous site to evaluate and take forward the most successful components
Competitor review to identify best/worst practice and identify opportunities
Key personas were developed to cover the diverse audience needs
More than 75 high-fidelity interactive wireframes were created
20 rounds of iterative usability testing using strict task tracking to monitor changes
200 participants recruited using Bunnyfoot’s expert recruitment company Bunnyfield
Iterative changes to wireframes based on customer feedback during testing
Visual design of an icon library featuring 100s of icons to help serve content creators
Full visual design of the new site working closely with easyJet’s Marketing and Branding team
Comprehensive design guidelines and templates were produced to support consistent content production
Engaged with the full variety of internal stakeholders including Marketing, Brand, Development, Legal teams. As well as working closely with external development teams associated with the projects
Worked collaboratively with the easyJet team developing a close and long-standing relationship
GAIN draw on their in-depth knowledge of customers and our sector to challenge us with better solutions. Their style mirrors our own – can do, delivery focused and not a Frappuccino in sight!
