Egypt-Specialist ETI concludes migration to OTDS

The Frankfurt-based tour operator ETI Express Travel International successfully concludes the migration to the Open Travel Data Standard (OTDS). After finalizing the hotel-only data it took only little more than two months to also migrate the production of package travel to OTDS. The lean data standard OTDS allows for ETI to deliver significantly more offers to the distribution systems than with the formerly used format INFX. The daily data deliveries to Traveltainment today contain 290 million data records for offers; before OTDS it totaled only 80 millions. Hence ETI’s chance to serve a customer’s search request with a matching offer […]

What is the OTDS format capable of and what makes it so special?

How does OTDS support tour operators and sales channels?

Strengths of OTDS - The data format OTDS is designed to improve the transmission of provider’s product data such as tour operators, airlines, rental car companies, or other supplier to the distribution systems that process those data for the use in travel search tools used in travel agencies or in travel website booking engines.


OTDS significantly minimizes the production time for data exports of tour operators or their Inventory Management Systems. Compared to the standards used to date such as INFX or KATI the production time is reduced by at least 75 percent. In addition incremental updates allow for deliveries of parts of the portfolio with the corresponding reduced file generation time.


Thanks to OTDS tour operators and other provider may decrease the volume of their data delivery to distribution systems significantly: In practice sizes for OTDS-files reach no more than 10% of the size for INFX-deliveries containng the same amount of offers. As with OTDS rather price- and product rules than complete offers are expressed, considerably more offers can be transferred in even smaller files. The effect on transfer- loading times is correspondingly positive – while at the same time data quality is pushed to a higher level.


Due to the precise definition of price- and product rules by the tour operator in OTDS there is no scope for interpretation when processing the data. As a result the data quality increases – trips are displayed with reliably calculated prices and availabilities within the consulting tools of travel agencies and in the IBEs. Also total prices for families are feasible.
In general with OTDS 95% of all prices are identical with those of the booking request. More that 90% of the trips are available and bookable.

Free of charge

OTDS as the open, nonproprietary standard is available free-of-charge and may be used by any tour operator- and distribution system – regardless of the technology deployed (e.g. central caches or local player). This ensures independence from proprietary data standards or -formats for tour operators and distribution systems.


OTDS already allows the transfer of all data for the most relevant travel components accommodation, flight, packaged travel as well as add-on services such as transfers, rental cars, insurances, activities, or parking lots. In addition OTDS contains all product- and price rules necessary for correct price calculation. All relevant information needed for product display, availability check, booking requests and the booking itself are also included.


OTDS is compatible for various systems: it is the powerful standard of choice for providing travel data to central cache systems as well as all filling players located in the sphere of the supplier. OTDS also supports different external attribution systems for describing the travel products such as Giata Facts and DRV GlobalTypes.

The leading distribution systems in the German market already interpret and process OTDS. By doing so, the optimized data are available within their frontoffice tools for travel agencies as well as in their internet booking engines. The tour operator webpages also can be equipped with the enhanced OTDS-data, so that customers searching for travel offers in travel agencies or in the internet can rely on meaningful offers with reliable pricing and availability information and including add-on services. The OTDS format allows for significantly more details, options, room- and flight alternatives.

Families can rely on the total price of a trip when transmitted with OTDS from the very first display on. Price corrections resulting from booking requests are omitted thanks to reliable adult- and children prices and explicit rules for the price calculation in dynamically packaged travel offers.

The travel industry works with a large number of data formats. Those formats help to display the countless travel offers of tour operators and other provider that reach the consumer via various distribution channels. All information about a trip are being processed so that the IT systems within the distribution chain can depict those data.
But the travel wishes of the consumer today are much more individual than ten years ago – the travel offers have to meet this change. And also tour operators and other supplier, online portals and travel agencies expect more from the technology they use. Legacy data formats today cannot fulfill those expectations anymore.

So far provider in the travel industry had to translate their travel offers into several data formats in order to supply the various distribution channels. In spite of the many formats the provider often did not succeed in highlighting their specific competitive advantages: the one format lacks a space for submitting taxi transfers, the other format cannot deal with child price reductions or specific child care offers.

So a new, common, open format was needed that delivers all relevant information regarding a travel offer into all distribution channels. This is precisely the intention of OTDS. At the same time it shall reflect the requirements of as many market player as possible and refine itself as an open data format. Thanks to the cost-free download at this website OTDS is freely accessible to all interested travel organisations and thus can establish itself as the future market standard.

OTDS versions - OTDS 1.0 was published by the OTDS association in April 2012. Within this first basic version the travel components accomodation, flight, packaged travel and add-on services such as transfer, rental car, parking, insurances etc. together with all the implicated product- and pricing rules already could be represented.

The current version OTDS 1.9.3 excels by comprehensive options for flight prioritisation and rules for rounding amounts of money. Together with the multi-currency option and further diversified possibilities for rental cars and insurances those criteria meet the requirements of many tour operator regarding an efficient and extensive display of their travel products in the distribution systems.
