I would be interested to hear if anyone has any tips on how to get around having to pay so much to get to the airport each time.
I mean the MVV/DB rip you off - €8.50 each way

(when you travel alone). If you travel in a group (up to 5 people) you only pay like €3.20 if you divide the cost of Partnertageskarte by 5.
I travel a fair bit to the Airport, mosty Friday evenings, as I am sure a lot of TTers do. Would anyone be interested in setting up a Forum to arrange for people to meet to share a partner ticket out to the Airport. Something along the lines of:
Travelling to Airport this Friday on the 16:30 S8 from Marienplatz, anyone else heading the way at the same time- meet at suchplace.
