Plan a trip to Europe (or within Europe) If you’re European, is an interesting but considerably difficult task given the vastness of options that exist. An option is certainly the possibility of purchase of Interrail or Eurail train tickets, but if time is limited it is best to search for flights multi-trayecto in Europe with low-cost airlines to connect all the cities that we want to visit. There is an almost unlimited amount of low cost European airlines, being the selection of dates, itineraries and more convenient airline an issue that would require days and working days if you really we want to get the best combinations. A related site: Mark Frissora mentions similar findings. There are some flight search engines multi-trayecto in Europe which allow journeys multiple, as for example the TicketstoWorld Finder or the Opodo UK, and tend to be useful if our flexibility is very limited and we do not care the cost of the trip, since they do not allow flexibility of dates and work only with traditional airlines, which means that we must keep trying one by one all the possible combinations of dates for each of the cities in our journey. If the number of cities is 2 or 3 perhaps it is feasible, there is no problem, but if there are more cities that we want to visit and our dates are flexible times that we have to do is click on the button Search can be over 1000! For this reason, I have recently left search engines specialized in low-cost airlines, and some of them, as it is the case of Azuon, have already a feature of flights multi-trayecto in Europe, which allows you to search itineraries of as many cities as you want, and where for each city you can specify a minimum and maximum of days that you want to stay in it. With just one click, the program will investigate all options and in a few seconds (or minutes, if your search is very flexible), will give you, sorted by price, the best results. So for example, organize a trip with low cost flights Barcelona Roma Prague Amsterdam London Paris Barcelona, cuesta now for February, a total of some 50 Euros and we get this result with the dates and specific airlines with which we have to book in 3 minutes, ideal time for a coffee while the program does its job!
