After you have put together the trip, it will be displayed on the left side. At the top, you will find the navigation which will guide you through the steps. You always start with the flight connections for the individual routes.
The LH direct flight is pre-selected for the journey from Frankfurt to Barcelona. Clicking on this flight will expand the detailed information.
Alternatives, such as the earlier LH flight, or a Flixbus connection, can be selected directly from here. Click on "OTHER OPTIONS" to see more alternatives.
The list of alternatives can be sorted or filtered as desired.
If the result meets your requirements, click on "CONTINUE" at the bottom of the page or on "HOTELS" in the navigation and you will be taken to the hotel selection.
