Lux Airport is the most convenient way of air traveling to Luxembourg (Findel airport). The national carrier LuxAir is a very decent option. From the airport, it's only 20 minutes to the city centre by bus. A good choice is to take bus 16 (€ 2 / ticket). Our experience is that a taxi from the airport to the city centre can easily cost € 35. With the HOTCITY app you can check the bus arrivals and departures in real time.
Frankfurt Hahn. Several budget airlines fly to this German regional airport, that is 1 hour and 50 minutes away from Luxembourg by shuttle bus. Expect to pay about € 30 for a bus return ticket Frankfurt Hahn - Luxembourg.
Charleroi Airport. This regional airport in the south of Belgium, sometimes also called "Brussels South Airport" hosts Ryanair as well as several other budget airlines. Luxembourg City is 2 hours and 15 minutes away by a shuttle bus service which uses a pricing scheme similar to that of budget airlines (book early!).

Participants traveling on a really tight budget can also come by coach. Eurolines Netherlands offers return tickets starting from € 28, to those that book early.
The bus network in Luxembourg is well distributed and efficient. The conference site is located at the nearest bus stop "Stadgronn-Bréck". You can easily find your way at this site. With the HOTCITY app, you can find the nearest bus station and view the bus departures in real times. The HOTCITY app allows you also to buy your bus ticket with your smartphone.
Bus tickets come in two forms:
One way tickets, valid in Luxembourg of a period up to two hours.
Day cards, valid for all trains and buses in the entire country
Another interesting local transport alternative is to move around by bicycle. The City of Luxembourg has several fully automated bicycle rental stations, including one that is nearby the conference site. A subscription for one week costs only € 1.
Maps of the city of Luxembourg are available at pretty much every newspaper stand. Free maps, covering only the city centre and Kirchberg, are available at the Luxembourg City Tourist Office.
