Always listen to the experts!
They tell you that it is impossible
and why you can not do it.
When you know that: Go Ahead!

You can contact us by eMail (firstname@...) classic phone at +49 (531) 2957 5259, via Skype ( or WeChat (BarthelEU). We are also available on FaceTime, Viber or WhatsApp (number on request). For info about the geographic coverage of our data, please check here.

Aside our News-Blog, we also maintain a company page on LinkedIn, where we also post the latest news and developments, raise and answer questions and generally communicate with our followers. If you are interested in such information we encourage you to follow us there!

The Mission provides instant and affordable insight to high quality, competitive airports' catchment area analyses, enabling understanding of the ground based potentials. Just as MIDT-like data enabled this for passenger based analyses. With the difference that this works also for route feasibility studies where no previous MIDT data exists.

The Team

Yulia Barthel (owner)Jürgen Barthel
With the analyses provided on our website being completely automated, as the owner I handle all inquiries, issue invoices and also run some of the more complex analyses. Mostly I update the statistical data. As a 30-year veteran in aviation, logistics, IT and marketing, I support my wife Yulia as needed. I also help Yulia naturalizing the data we receive from a number of sources and to decide which numbers to take from the numbers game.

Our sincere thanks also go to the supporters of our development, namely our mapgician Stefan Schramm, our mathemagenie Ori Pomeranz, the supporters of our crowd-funding early 2015, Niall McCabe, Oli Arzt, Michael and others. Our thanks goes to all the people at UBM Routes for the support with ideas and video footage for our teaser video. For more such footage, also thanks to kind authorization given by British ATC NATS. Thanks also to Cora, Mathias, Reimar for their very good ideas, as well as the legion of people working at national statistics and cadastre offices as well as Eurostats we bothered throughout the past four years.

User Data

Personal Data, Cookies, etc.

Our site uses "Session"-Cookies to identify users that have registered to use our free and commercial B2B-services. These cookies are set upon login. Before login the cookie only sets the airport and does not contain any user data.
Our News is built using Wordpress using the Editorial Theme; source solutions, using their own cookies. We have no influence on the cookies used here, but they do not save personal information we know of.

Our Apache server generates log-files that we use only for error-management. We also occasionally generate classic automated analyses using open source tools like Webalizer. Those analyses provide us neutral information only, such as searches that were used to find us, the entry pages, the interest of our users in certain analyses or which countries our users come from. None of the analyses allow us to identify the user or the company.

For our users, upon registration we store the e-Mail, name, company and phone number. We also add some common information like the company mail address or associate users of the same company to each other to allow sharing of paid services. All other data we associate to the user profile is internal settings associated to the user, such as company logo icon used in the map, color preferences and preferred airport.
We also store illegal access attempts and keep the blacklisted e-Mails in our user table to block future attempts.

Jürgen and Yulia use a NextCloud address book on our own server in a SSL-secured internal environment.
That NextCloud is not used or linked into the website.
That address book does not only contain our contacts, but also contacts from other work and private contacts and is synchronized with our address books on our smart phone, our PC-based Thunderbird and our tablets. The address book contains public data from business cards, business networks like LinkedIn, Routes, etc. We may also save personal information made available to us by yourself in our communication, though only on our personal address book. Such information is not part of the profile data saved on

If you would like to know what data we have in our address book, please contact us.

At no time do we ask your password; we can only reset it to force setting a new password. Nor do we ask you for or save any payment data. We issue invoices and leave it to you to select how to process the payment. We plan to add an automated payment process using PayPal or a similar service. In that case, we also will not save any payment information beyond the fact if/that certain services have been paid for.


All Information on has been compiled from official sources, such as Eurostat and the national statistics and cadastre offices, information received directly from airlines, airports and their associations, Wikipedia, OpenStreetMap and other information publicly available on the Internet. If you have questions about our source of specific information, simply contact us, to avoid copyright claims, we do keep file of our sources.

As with all large data amounts being compiled from individual, varying sources, despite all reviews and bugfixing efforts, errors may happen. As such, we expect you to inform us of any errors that you identify or assume and we will verify and if necessary correct them as quickly as possible! As we find such errors often also in the source data and we correct such errors frequently ourselves, we take no liability resulting from such errors on our data, except if they have been the result of gross or wilful neglect on our side.

Images + Data Used

Throughout our activities, we happily refer to a quote by Richard Branson which became our Mantra in the development of The quote was originally published in 2012 on Twitter, the image published on the referred page - this page does no longer exist. Despite our understanding of rightful use of the quote/image published there, we unsuccessfully tried to contact Virgin/Mr. Branson for an official approval. Should you represent Mr. Branson and wish us to remove this quote, please contact us!

In our teaser video we used movie footage we registered at Pond5 as well as free footage courtesy UBM Routes and British ATC NATS.

Airport or Airline Logos or images used remain the sole property of their rightful owners. As mentioned in the disclaimer, we do keep file of our sources, so in case of concerns, simply contact us at your convenience!

In the print detail page we also provide the Seasonality Variety in Demand factor. Excel tool can be found on

The national cadastre offices of Croatia, Denmark, Portugal, Romania, Scotland and the United Kingdom have kindly provided municipality-level map data that we use within our mapping applications.

External Links

Our collection of links is incomplete. We take no warranty whatsoever for the links to work as external links happen to get updated without them notifying us. If you miss a link or encounter a dead link, simply inform us. We love to hear from you!

We refer to information in and their Route Shop, as well as the Route Exchange for airports. This is a link into these services, as we do not intend to duplicate their (commercial) information. In case of and The Hub we sometimes use their information to manually double-check some own data as a quality control measure.
In case of Wikipedia, we extract the extract of their airport pages using the Wikipedia API. We keep a cached copy of this information that we recheck now and then, so updates may not be instantly refreshed. We do work to complete the Wikipedia references, if we don't link a specific airport yet, please let us know.

As we run large amounts of data, we cannot review all external websites. We had cases where the official link changed, we usually use links that are also used in Wikipedia. Should there be (legally) questionable links, please do inform us so we can check and take the approbriate action.

Aside usage of OpenStreetMap's Administrative Boundaries and Leaflet, we have also received detailed map data so far courtesy of the cadastre administrations of Croatia, Denmark, Portugal, Romania and the United Kingdom.
