(Germanwings, HappagLloydExpress, LTU, Air Berlin are particularly cheap). From there take the
[[http://www.stadtwerke-bonn.de/index.php?id=442|express bus to/from Bonn main station]] (travel time approx. 20 minutes, costs 6,50 Euro). If you want to come directly to the university or my home get out immediately at the first stop, "Innenministerium". I'll come and pick you up there (if you let me know). If you are heading for a hotel in the city center, get off at the last station, "Hauptbahnhof" (= main station). * International: [[http://www.airportcity-frankfurt.com/cms/default/rubrik/9/9682.airport_city_en.htm|Fly to Frankfurt (FRA)]] and from there [[http://www.bahn.de|take a train]] to Bonn main station. * By public transport (e.g. from Cologne/Bonn Airport): see [[http://vrs-info.de|VRS]] and its [[http://188.8.131.52/ass/client/vrs/fahrplanauskunft.html|multilingual timetable search]]
You're welcome to ask me for help if you have questions, special requirements or simply want a cheaper option than what's listed online. In the latter case the youth hostel overview might be interesting for you. The first one on that page, the CJD, is particularly convenient if you want something that is close to the University and my home.
