About us

BookSmart24 is a new global travel booking app focused on making travel more sustainable. We help travelers find the most climate-friendly way to travel. We use technology to compare and analyze travel options so consumers have the information they need to make the right choice.

Our proprietary flight and travel booking systems analyze the environmental impact of each trip and prioritize the most climate-friendly option for easy selection. Duration and price are compared to each trip's individual carbon footprint. In this way, the best travel option is offered between two points, with priority always given to flight plans with a low CO2 impact.  Note: It is NOT a CO2 compensation, but the actual avoidance of CO2 emissions is the main focus.

As long as mankind does not reduce its emissions to zero, global warming will continue to increase. Carbon dioxide, methane and other greenhouse gases must be reduced.  BookSmart24 starts with flights and expands to trains and all other modes of mobility, combining them in the most efficient way.

Our vision is to quickly become the world's leading reference portal for sustainable travel bookings.

Cookie Statement

Cookies and other tracking technologies can be used on our websites and apps in various ways, like making the website work, to analyze traffic, or for advertisement purposes. These technologies are either used by us directly, or by our business partners, including third-party service providers and advertisers we work with. If you want to learn more about what a cookie is, how they're used and what your choices are, you can read more here.

What's a cookie?

A cookie is a small amount of data that's placed in the browser of your computer or on your mobile device. So-called “first-party cookies” (not as much fun as they sound) are cookies served by the entity operating the domain through which the cookie is served. ’s own cookies are therefore “first-party cookies." In case we allow others to service cookies through the websites and apps, these cookies are so-called “third-party cookies."

In addition, there's a difference between session cookies and permanent cookies. Session cookies only exist until you close your browser. Permanent cookies have a longer lifespan and aren't automatically deleted when you close your browser. We strive to serve cookies or allow the serving of cookies with a maximum lifespan of 5 years. Only in exceptional circumstances, like for security purposes and where absolutely necessary, will a cookie have a longer lifespan than that.

In addition, other tracking technologies are used which are similar to cookies. These can include web beacons (also known as pixel tags, web bugs, or gifs), tracking URLs, or software development kits (SDKs). A web beacon is a tiny graphic image of just one pixel that can be delivered to your computer as part of a web page request in an app, in an advertisement, or in an HTML email message. Pixels can be used to retrieve info from your device, like your device type or operating system, IP address, and time of visit. They're also used to serve and read cookies in your browser. Tracking URLs are used to understand from what referring website the websites or apps are used. SDKs are small pieces of code included in apps that function like cookies and web beacons.

All these technologies together are referred to in this Cookie Statement as “cookies."

How are cookies used?

Cookies are used for different purposes. They allow you to be recognized as the same user across the different pages of a website, between websites, or when you use an app.

Our website and apps use cookies for different purposes:

Technical Cookies: We try to give our visitors an advanced, user-friendly website and apps that adapt automatically to their needs and wishes. To achieve this we use technical cookies to show you our website, to make them function correctly, to create your user account, to sign you in, and to manage your bookings. These technical cookies are absolutely necessary for our website to function properly.

Functional Cookies: We also use functional cookies to remember your preferences and help you use our website and apps efficiently and effectively. For example, these cookies remember your preferred currency, language, your searches, and your previously viewed accommodations. We may also use cookies to remember your registration info so you don’t have to retype your login credentials every time you visit our site (because let’s face it – that gets annoying). Your password will, however, always be encrypted. These functional cookies are not strictly necessary for our website to work, but they make it easier to use and enhance your experience.

Analytics Cookies: We use these cookies to gain insight into how our visitors use. This means we can find out what works and what doesn't, optimize and improve our websites or apps, understand the effectiveness of advertisements and communications, and ensure we continue to be interesting and relevant. The data we gather can include which web pages you've viewed, which referring/exit pages you've entered and left from, which platform type you've used, which emails you've opened and acted upon, and date and time stamp info.

It also means we can use details about how you interacted with the site, like the number of clicks you make on a given page, your mouse movements and scrolling activity, the search words you use, and the text you enter into various fields. We use analytics cookies as part of our online advertising campaigns to learn how users interact with our website or apps after they've been shown an online advertisement. This may include advertisements on third-party websites. Analytics cookies may also be used to enable our business partners to learn if their customers use accommodation offers integrated into their websites.

Commercial Cookies: We use third-party cookies as well as our own to display personalized advertisements on our websites and on other websites. This is called “retargeting,” and it's based on browsing activities like the destinations you've been searching for, the accommodations you've viewed, and the prices you've been shown.

What are your choices?

To learn more about cookies and how to manage or delete them, just visit allaboutcookies.org and the help section of your browser. In the settings for browsers like Internet Explorer, Safari, Firefox or Chrome, you can set which cookies to accept and which to reject. Where you find these settings depends on your browser – use the "Help" function in your browser to locate the settings you need.

If you decide not to accept certain technical and/or functional cookies, you may not be able to use some functions on our website. We currently don't support “Do Not Track” browser settings. In which case a common standard is developed that defines what exactly will be meant by “Do Not Track” browser signals, we'll review this policy again.

Terms and Regulations Concerning Your Travel Reservation / Flight Booking


Based on the fare, the airline may not allow any cancellations. The cheapest fares usually do not allow any changes and the cancellation charges are 100% of the ticket price. Moreover, the service fees paid to BookSmart24 for the reservation will not be reimbursed for any reason. You may request a refund and as long as it is allowed by the airline tariff, a refund handling fee of $50/40EUR per ticket will be charged by BookSmart24 or BookSmart24’s agents or fulfillment partners in addition to any other charge refund fee levied by the airline.


Airlines generally charge a fee for changes. In addition to this fee, BookSmart24 or BookSmart24´s agents or fulfillment partners will charge a $50/40EUR handling fee per person. However, we would like to remind you that based on the fare the airline may not allow any changes.

Travel Documents

In order to fly, you need to provide the required official documents (passport, identity card, visa, etc.). In addition to your passport, some countries also require a visa.

Please check with the relevant administrative authorities to fully understand the formalities you will need for trouble-free travelling and stay at your destination (passport, visa and vaccines etc.). It is your responsibility to comply with these formalities. You cannot request refunds or reimbursements if you are denied boarding or entry because you have not presented the required documents (passport, visa, vaccination certificate, etc.). It is the passenger's responsibility to have the necessary documents for travelling available at the time of boarding or at any other time as requested by the authorities or the airline.

Electronic Tickets (E-Tickets)

An electronic ticket or e-ticket is recorded directly in the airline's computer. No printed ticket will be sent to you but a link to your e-ticket in case you want to print it. You simply need to go to the airport with the required official document (identity card or passport) as well as your reservation number, and go to the airline's check-in desk to get your boarding pass.

Schedule Changes

It is possible that the airline changes a flight schedule. It is solely the passenger's responsibility to check flight times and reconfirm reservations, within 72 hours of departure. You, at any time, must check the status of your booking. Terminal or BookSmart24’s agents or fulfillment partners will not be responsible of any missed flights due to schedule changes by the airlines.

Reservation, Passenger Names

All reservations must be made in the name of the person(s) traveling - no nicknames. For international travel the name on the reservation must be EXACTLY as it appears on the traveler's passport. If there is a passenger name error it is not possible to change a name: we are obliged to cancel the ticket and issue a new one. This may entail losing the total amount paid for the original ticket.

Seat Assignments and Meals

Seat assignments and special meal requests will be conveyed to the airlines, but cannot be guaranteed. Seats for all passengers traveling together will be selected automatically and adjacent to the primary passenger, based on best seats available at the time of request.

Travel Destinations

Although most travel, including travel to international destinations, is completed without incident, travel to certain destinations may involve greater risk than others. Passengers are advised to review travel prohibitions, warnings, announcements and advisories Published on government websites or special travel advisories announced on the websites of embassies or consulates. By offering to some particular international destinations, BookSmart24 or BookSmart24’s agents or fulfillment partners does not represent or warrant that travelling to such points is advisable or without risk and are not liable for any damages or losses that may result.


We accept Visa, MasterCard and in most countries American Express credit cards. Tickets are always paid in Euros or US Dollars and charged to the customer in the currency selected in the website at the exchange rate applicable at the time of payment.
