The flight search
The easiest ever way to find cheap flights!
From the cheap flight by the low-cost airlines through to the business class ticket – checkfelix finds it all!
The travel search engine searches hundreds of websites by airlines such as Austrian Airlines, Lauda Air, Swiss, Alitalia, KLM, etc., and low-cost carriers such as SkyEurope, EasyJet, Ryanair, Air Berlin, FlyNiki, etc. as well as online travel agencies such as ebookers, lastminute.com, L’TUR, Opodo, TUI, STA Travel, etc. for the lowest-price flights.
checkfelix.com offers an easy-to-use search mask for entering all the parameters essential to the search for a flight.
With the aid of various search algorithms, the city finder ensures that incorrectly spelled city names are automatically corrected by the system and that the entry of three-letter airport codes can immediately be correctly assigned. The interactive world map displays all the scheduled flight airports in the world. It is the perfect aid for searching for alternative airports as well as for searching for airports in unfamiliar places.
By means of the 1-2-go calendar, you only need three clicks to quickly and easily enter the outbound and return flight dates:
Open – outbound flight – return flight – done!
checkfelix.com also offers an open jaw flight search, which enables the search for complex flights comprising up to four various routes. This means, for example, you only need one search for a flight from Vienna to London, London to New York and a return flight from Miami to London.
The flexible search finds the lowest-price flights within the space of up to one week. This means that one search can find up to 49 different flight combinations, also saving a considerable amount of time.
The "airport within a distance of..." function further simplifies the search. You are then shown results not only for Vienna, for example, but also for Bratislava or, instead of launching a search for each of Düsseldorf, Cologne and Dortmund, you only need to search once!
On the results page, the user finds a clearly prepared list which conveys all the necessary detailed information on the individual flights.
The search overview shows the user precisely how much longer the search will take, and how many flight offers have already been found.
The top-5 provider ranking and the filter function directly next to the results list help the users to select the best, cheapest flight.
It is important that all flight prices include all airport taxes and charges, and that the quoted price is the sum total for all passengers, for the entire trip.
The filter makes it possible to search through the results list to find the right product. Filter criteria are stop-overs, airlines, departure times, flight times and price. Furthermore, the results can also be sorted into various criteria such as price, flight operator or airline.
Whilst the user searches through the results list for suitable flights, the potential flights can be added to a favourites list, and unsuitable prices can be removed from the list. This guarantees the efficient sorting of the flight results.
By clicking on to "book", the user is forwarded directly to the booking page of the relevant provider, where the selected flight can be booked at the best price.
