The travel industry popularized many of the features so common across e-commerce websites. Let’s look at some of the typical features you’ve come to expect from the best travel e-commerce websites.

A summary of common features leveraged by the best e-commerce travel websites is illustrated in the table below.

Customer convenience

How did consumers book tickets, airfare, or accommodations before the internet? Travel arrangements required extensive planning via phone or in-person meetings. Without the assistance of travel agencies, consumers were required to coordinate plans with multiple points of contact — cabs or rental cars, airlines, and hotels.

E-commerce travel websites simplify this process. Instead of painstakingly coordinating an itinerary between multiple sources, consumers may plan, price shop, and purchase fares and lodging from or through one specific vendor.

Loyalty programs and incentives

Frequent flier programs are believed to have been introduced by Texas International Airlines in 1979 before being embraced further by American and United Airlines in 1981. In 2017, 91% of OTAs maintained a loyalty program.

Travel e-commerce websites use data analytics and insights to personalize offerings from intricate partner networks. Customers who participate in these programs earn anything from free or discounted fares, special rates on rentals and accommodations, and even discounted liquor, flowers, or health insurance.

Competitive pricing

Around the time travel e-commerce websites began to take off, airlines realized unsold seats could be sold at discounted rates by consolidators and auction houses. This appealed to flexible customers who preferred low fares over minimizing flight times and layovers.

Some e-commerce travel companies eventually adopted dynamic pricing to automatically adjust the cost of fares, lodging, and reservations. Leveraging personalization allows travel sites to “be more competitive” and respond to real-time market conditions while offering customers the ability to search for and choose offers that fit their budgets and needs.

Search filtering

Planning for travel is highly personal — no two customers’ journeys are the same. Travel e-commerce websites provide customizable search filtering designed to provide real-time information based on a customer’s requests, preferences, and needs.

Some companies, like Kayak, go the extra mile by providing charts to compare median prices based on historical data, destination, and travel dates. Responsive and useful search filters allow customers to easily find the results they’re looking for when planning their travel itinerary, guiding them further along the sales funnel.

Simplified checkout

Airline and travel e-commerce websites have some of the highest cart abandonment rates in e-commerce, at 87.87% and 81.31%, respectively. (For comparison, the average cart abandonment rate of online stores is 69.8%.)

OTAs and travel companies understand that cart abandonment stems from inefficient user interfaces and too much choice. By keeping the checkout process simple and limiting choices to the best offers, e-commerce travel websites may improve conversions and reduce abandonment.
