Best online travel agencies for business travel

First, let’s take a look at the top online travel agencies for corporate travel. There’s plenty on offer, but we’ve compiled our top three.

1. TravelPerk

TravelPerk is a modern solution for modern corporate travel. It offers a wide range of options for flights, hotels, car rentals, and trains, all in one place. The platform is simple to use, whether on the web or via its mobile app. The platform is accessible via both web and mobile apps, and it features transparent pricing—customers only pay when they travel, avoiding hidden fees.

TravelPerk is praised for its customer support, which is available 24/7 with a 1-minute target response time.

This makes managing travel both efficient and eco-friendly.

Main offerings and features:

TravelPerk gives employees access to the information and the security they need to travel with peace of mind. It also gives organizations and travel managers access to competitive corporate travel rates.

2. SAP Concur

SAP Concur has been around for years—since 1993—and is trusted by many businesses to provide comprehensive business travel solutions. Its technology is self-owned and managed, meaning there’s no back and forth with third parties for changes or updates.

Main offerings and features:

Works with some of the biggest brands

Easy tracking and reporting of expenses for expense reports

Many connected apps, such as Uber and Airbnb for cars and hotels

One solution for a variety of business travel spending

SAP Concur is a great tool for organizations looking for a traditional approach to business travel. However, it requires patience–the platform takes 6-8 weeks to implement and user onboarding in order to make the most of it. Plus, some users report that the UI is outdated, making it a less enjoyable experience for business travelers.

Here’s why you should upgrade to TravelPerk from SAP Concur and experience the difference today.

3. MyCWT

MyCWT is CWT’s corporate travel management solution. Its dedicated industry and country specialists ensure your employees are well looked after wherever they are.

CWT’s been in the travel industry for over 150 years, but MyCWT is an experienced travel management solution for business travelers everywhere.

Main offerings and features:

Ample integrations

Award-winning mobile app

Employee-centric travel management

MyCWT is a great solution for companies with a bigger budget and big corporate travel needs. They do, however, use third-party software to deliver deals to business travelers and organizations—meaning updates and changes to the software can take time. There’s lots of back and forth that slows down progress and platform development.

Best online travel agencies for leisure travel

Now, let’s take a look at online travel agencies for leisure travel. These are websites used by the everyday user to book their next big holiday or family vacation—whether that's to New York or the Caribbean.

Note: We’ve included our top picks for OTAs specializing in flights at the bottom of this section—if you prefer to jump ahead.

4. Booking.com

Booking.com is a leading online travel agency known for its extensive selection of hotel rooms and travel services. With millions of listings, it provides options ranging from budget hostels to luxury hotels, making it easy for travelers to find the right fit for their needs.

The platform’s user-friendly interface allows customers to search, compare, and book accommodations effortlessly. Additionally, Booking.com offers various travel services, including flights, car rentals, and airport taxis, all integrated into one convenient platform.

Main offerings and features:

Intuitive booking tool and website

Flight + Hotel booking for easily planning trips with no cross-referencing travel websites

Simple car rental options and taxi hire

Available in over 40 different languages and offers over half a million properties across 207 countries

You can book experiences in your destination city to entertain you on your travels

Genius rewards program

Overall, booking.com is a comprehensive online travel agency with hotels and flights anywhere in the world.

That being said, some users share instances of booking fake listings, causing travelers to show up at properties that aren't actually available for rent. Some users also claim that initial prices shown with discounts often differ from final booking prices—sometimes by hundreds of dollars.

5. Agoda

Agoda is a prominent online travel agency (OTA) offering everything from hotel bookings to flights, airport transfers, and activities. As part of Booking Holdings, Agoda taps into a massive network of over 4 million hotels worldwide, with a strong focus on the Asian region and a growing global presence.

One key feature is the "Best Price Guarantee," which promises that you’ll get the lowest rate available for a hotel room when booking through Agoda. If you find a lower price for the same accommodation on another website, Agoda will match or beat that price—a pretty bold claim.

Main offerings and features:

Simple interface and booking tool

Deals when making more than one booking

38 different languages and offers a 24-hour, multilingual customer support service

Free cancellation within 24 hours of booking

Millions of reviews to help make your decision

The flight search and booking process tool isn’t as user-friendly as some dedicated booking platforms. Some customers have experienced technical issues when booking flights, including payment failures and unexpected booking confirmations.

6. Lastminute.com

Lastminute.com offers various travel services, including flights, hotels, car rentals, and complete holiday packages. These packages cover everything from lodging to meals and entertainment. The platform is particularly well-known for its last-minute deals, providing travelers with significant savings on bookings made closer to the travel date.

A unique feature of Lastminute.com is its dynamic holiday packages, which allow users to customize their trips by combining flights, accommodations, and additional services in one booking. The platform’s user-friendly interface and mobile app further streamline the booking process, making it easy for users to find and secure great deals.

Main offerings and features:

ATOL protection on flight + hotel bundles

Flash sales for last-minute deals

Payment plans to spread out the cost of travel

Extra entertainment booking for your trips, like theatrical productions and day trips

Gift cards for gifting travel

However, despite its strengths, some users have reported issues with unresponsive customer service and difficulty in getting refunds for canceled bookings. Some users also claim that bookings are not properly confirmed with airlines or hotels. This suggests it’s wise to double-check reservations directly with service providers when using Lastminute.com

7. Expedia

As part of the Expedia Group, which also owns brands like Orbitz, Travelocity, and Hotwire, Expedia benefits from an extensive network of distribution channels. Expedia’s booking engine is designed to be user-friendly, making it easy for travelers to search, compare, and book trips that fit their preferences and budget.

Expedia rewards for hotels, cars, and more

Experienced support

While Expedia is popular for its offerings, some users have complained of poor customer service. when problems arise, such as flight cancellations or hotel booking issues, customers are often directed back to Expedia instead of the service providers, complicating the resolution process.

5. Hotwire

Hotwire, a subsidiary of the Expedia Group, is known for its focus on providing discounts on hotel rooms, flights, and car rentals. Hotwire offers "Hot Rate," where travelers can book discounted rates without knowing the name of the hotel or car rental company until after the purchase.Hotwire's search engine is designed to quickly scan for the best deals across various categories, making it easy for users to find affordable travel options.

Main offerings and features:

Book hotels, flights, cars, and bundles

24/7 support

Lower prices on the app

Great last-minute deals for spontaneous travel

If you’re booking last minute, consider doing it with Hotwire. However, some users report that the advertised savings on "Hot Rate" hotels aren't always as good as claimed or that they could have gotten similar rates with direct booking. A few travelers have also reported being assigned to low-quality hotels that didn't match the advertised star rating.

9. Bookmundi

What sets Bookmundi apart is its focus on adventure and cultural experiences, making it an ideal choice for travelers looking for more than just the typical tourist spots.

11. Kiwi.com

Kiwi.com is particularly known for its proprietary "Virtual Interlining" technology. This allows travelers to book connections between airlines and other transportation providers that do not traditionally partner with each other.

This approach enables users to find unique routes and often more affordable travel options unavailable through traditional booking methods.

One of the go-to features of Kiwi.com is its "Kiwi.com Guarantee," which provides protection for travelers in case of missed connections due to delays or cancellations, even when the trip involves multiple carriers.

Simple flight booking tool

Easy-to-use app

Kiwi.com is an innovative OTA—perfect for city-hoppers and the travel-hungry. Be wary, though—some reviews claim that cancellation is tricky and customer service can be unreliable.

How do online travel agencies work?

An Online Travel Agency (OTA) is a website that sells travel-related services like hotels, flights, and car rentals from one central location.. They're the digital equivalent of a travel agent.

These platforms offer a broad selection of options by aggregating offerings from various service providers—hotels, airlines, and car rental companies—who pay OTAs for the visibility and reach they provide. For travelers, this means they can compare prices, read reviews, and book everything they need for their trip in one place, often securing better deals due to the competitive environment OTAs create.

What are the advantages of booking through an online travel agency?

Here are some of the benefits of booking travel services through an OTA:

Access to comparison tools

Peer reviews to help you with your decisions

Flexible cancellation policies

All your travel in one place

Local flights and deals

Rewards programs

These benefits are why OTAs are so popular with travelers worldwide, and why you want to consider finding the one that works best for you. Here are the details you need to have in mind before considering the corporate travel services of an online travel agency:

Access to comparison tools

The main advantage of using an OTA is that you can quickly and easily compare the prices of accommodation, flights, and more. Most have search filters and comparison tools so you can target your search and find exactly what you’re looking for.

Peer reviews

Another benefit to booking through an online travel agency is the review system, whereby users leave ratings and written reviews for future customers. The option to leave a review is usually only available after a user has booked a service, so they’re a reliable source of feedback.

Flexible cancellation

To be featured on an online travel agency, hotels, airlines, and other service providers often must adhere to the OTA’s cancellation policy. All of the information is clearly laid out for the customer in an email or on the website upon booking, which makes it very user-friendly and customer-centric.

Note: Not all OTA’s have their own cancellation and change policy—some, like Skyscanner, take you to the vendor’s website to confirm your ticket. This then means you’re subject to the vendor’s cancellation and changes policy, which may not be all that flexible.

Cancel anytime, anywhere. Get 80% of your money back.

One account for all of your travel needs

You can also use one account for all your different travel planning, saving the hassle of entering details over and over again. Remember: a good OTA is an intuitive OTA—you want to be able to easily navigate your options without the need for constant support.Again, some platforms—mainly aggregator sites—will send you to a third-party website for booking. This means you’ll need to liaise directly with the third-party for any changes.

A local approach to global travel

OTAs personalize things like measurements and currencies to improve the individual user’s experience. Consequently, independently run establishments that may not have the resources to adapt their website internationally are unable to compete.

You’re offered the best deals for your area in a currency you know—making sure everything’s crystal clear when it comes to booking.

Rewards programs

Lots of online travel agencies offer reward systems, such as Booking.com and Expedia. These offer frequent users access to special deals and discounts—much like the rewards programs you get with an airline or hotel.
