Which Airport?
//EDIT//
Schönefeld! OK!!! I check a connection for you!
//EDIT//
Allrigth,
you have to take the train at 05:31 h from "
Hellersdorf" to the direction"
Alexanderplatz (Line U5)". You leave the train at "
Frankfurter Allee" at 05.51 h. Now you have to take the train "
Ring (Line S41) (Clockwise)" (DONT TAKE RING 42 - wrong direction!!!) at 05.56 h and leave the train at "
Treptower Park" at 06:02 h. Now I think you just have to switch to the other rail and take the train at 06:02 h (so the train should be allready there). Direction is "
S Flughafen Berlin-Schönefeld (Line S9)" and you will arrive at 06:31 h at "
Flughafen Berlin Schönefeld".
Here is a picture of your route:
