“Flight Delay Guarantee” is a paid service that provides the ability for a user that had their flight delayed by 1h or more, or canceled by the airline, with the choice between rebooking their disrupted flight on any airline or getting a full refund for it, therefore achieving peace of mind during their trip.
Flight Delay Guarantee is one of Hopper’s Fintech products, and was also one of the biggest revenue generators for the company. As a Senior Product Designer in the Disruption team, I designed multiple rapid experiments with a focus on re-merchandise Flight Delay Guarantee to increase revenue within a tight timeline, tracking results by creating prototypes with low-code tools such as Webflow, and collecting user feedback quickly. The experiments led to a more than $1 increase in Revenue per Transaction.
I have omitted confidential information in this case study to comply with my non-disclosure agreement.
In this case, we used rapid experimentation to increase revenue for the Flight Delay Guarantee product, our coverage that protected users against flight delays and cancellations and gave them the option to rebook their disrupted flight or get a refund for it.
Previous surveys had shown that customers had different needs for different types of travel, so we wanted to experiment with combining the ability to choose your coverage and the price for it. The hypothesis was that we had the potential to reach even more users if they had the flexibility to choose their coverage.
Our research showed that users believe that cancellations are the airline’s responsibility and they shouldn’t pay to have coverage against it, while coverage against flight delays was a great deal -it sounded too good to be true!
Users shared that having a small difference in price between two options, where one is a single coverage (like delays) and the other is a combined coverage (like delays + cancellations) made the combined option look better ($5 more) — they said that the price difference was too small to not add it.
So we ran our smoke tests:
These experiments combined led to an increase of over $1 in revenue per attach for the Flight Delay Guarantee product, successfully achieving our goal to increase revenue.
The current design of the Flight Delay Guarantee offer was a bottom sheet presented on top of the Confirm Itinerary screen, and there the users had the option to “Add to my trip” or decline it with
“No, thanks”.
Previous surveys had shown that customers had different needs for different types of travel, so we wanted to experiment with combining the ability to choose your coverage and the price for it.
The hypothesis was that we had the potential to reach even more users if they had the flexibility to choose their coverage.
We collected qualitative feedback to understand how users felt about the new coverage options and to evaluate the usability of the designs. We were able to collect user feedback asynchronously through unmoderated user interviews and usability testing and get an insight report within 2 days.
Cancellations are the airline’s responsibility ✈️
Most users don’t see much value in purchasing coverage against cancellations for their flights since they believe it’s the airline’s responsibility to compensate the customer for cancellations caused by them, therefore, they shouldn’t have to pay more for it (a total of 11 users out of 20 that were interviewed).
Our initial hypothesis was that users would be interested in purchasing coverage against cancellations since it is a more disruptive event than a flight delay, but this research proved otherwise.
Important to mention that the reality in the U.S. is a bit different from their expectation — as of 2023, there are no federal laws requiring airlines to provide a refund for canceled flights (Source: U.S. Department of Transportation).
Coverage against flight delays is a great deal 🕒
Users were surprised to read that they could purchase protection against flight delays of only 1 hour long and be able to rebook their disrupted flight or get a refund for it.
A common quote was that “It looks too good to be true”.
A small price difference made the “upgrade” option look better 💰
One of the variants tested an idea of breaking the current Flight Delay Guarantee product that covered both flight delays and cancellations into 2 different options: one where we offered a single coverage for a smaller price and one where offered both of them (delays + cancellations) together for the current price.
We used a $5 difference between the single and the upgraded option and as a result, users perceived the upgrade one as a better deal because the price difference was “too small to not buy it and get extra protection”, making them feel like they would be wasting money if they added the single option only.
To run rapid and trackable experiments without the need for engineers to build the interface, I built 7 different variants we wanted to experiment with using Webflow (a low-code tool), and this allowed us to track the success of each variant once we launched it.
These are the variants we took to the first round of the smoke test:
As mentioned in the research section, this concept offered a single coverage for a smaller price and an option to add delays + cancellations, the upgrade option, for just $5 more. We had two variants: one where the single coverage was Delays, and one where it was Cancellations.
What if we broke the current coverage into 2 options so that users could choose what better fits their needs?
Only one of the two coverages was offered — Cancellations or Delays.
The current Flight Delay Guarantee policy covered cancellations that happen on the day of travel and 1-hour delays.
From time to time we read on surveys that users wanted to be covered against cancellations that happen anytime between their purchase and departure. This variant gave them the option to choose between cancellations that happen on the day of travel coverage or a more comprehensive one, where they would be covered against cancellations that happen anytime between booking and departure.
This variant had the goal to understand if users would be willing to pay less for a 2-hour coverage instead of the current 1-hour coverage.
What if users could be covered against ANY type of disruptions during their trip? If you miss it because you arrived late, or the security lines were too long, really anything?
This is the idea behind the most comprehensive variant we tested:
By tracking the attach rate of each variant we found a winner: The upgrade concept.
The “upgrade concept” was the most purchased option 👑
Upgrade was the clear winner with both variants having the two highest attach rates.Based on the research, we learned that the small difference in price between the single and the upgraded option was perceived as too small to not add — it made the combo option look better.
Cancellation coverages had a good performance 👍
Even with users mentioning that they thought it was the airline's responsibility to protect them against flight cancellations, the Cancellation only and Cancellation coverage extension got 3rd and 4th place respectively in the smoke tests, losing to the Upgrade variants by a small percentage.
The Delays offers did not perform well 🕒
This finding was a total surprise — the two options that explored offering only a Flight Delay coverage (Delays coverage extension, Delays only) had low attach rates, and this is unexpected since users mentioned in the interviews that coverage against delays looked like a good deal.
Disruption for any reason had the worst performance 👎
Even more surprising was seeing that the most comprehensive coverage had the lowest attach rate.
There are a few hypotheses for why this has happened (looked too good to be true, not enough information was provided on the offer screen, the policy was too generic, …), but for the short-term, it meant that we wouldn’t explore this coverage option for now.
With the upgrade concept being the winner, I created a new design for the Flight Delay Guarantee screen, now incorporating the radio button options. For this experiment, we used the same two upgrade concept options and I built the new designs on Webflow, so we could track the success rapidly again.
The second-round winner was the Delays with Cancellations upgrade, which has become the new official offer for Flight Delay Guarantee.
We believed there was still more potential to be explored on the offer screen, and previous experiments ran by other teams at Hopper showed that using buttons to quickly add/decline an offer on the booking funnel could have an impact on the attach rate and overall booking conversion. With that in mind, we ran an experiment with the new official offer design that had a radio button to decline the offer, and one where they could easily add or decline it using the primary and secondary buttons, reducing the friction to move forward on the flow.
The radio button offer had a higher-priced option placed after the lower one, and with this experiment, we want to try changing the order because there’s a pricing psychology tactic that says:
The preselect won against the radio button. We ran comprehension surveys to understand if there was any difference in understanding what they bought, but no problems came up.
We also ran another experiment where we offer a Flight Delay Guarantee in a different placement of the booking funnel, but this case is WIP - stay tuned!
