Emerg. Exit Row on LH
 

Hello All,

I am flying out to Sarajevo from Chicago by way of the following flights next week on Tues.

UA ORD-BOS
LH BOS-MUC
LH MUC-SJJ

I would really like to get the Emergency Exit row (I was spoiled with that on a recently MH flight from KUL-LAX, and can't imagine travel w/o it again). What is the best way I can up my chances on getting this? Should I call ahead of time, or try at the airport? Furthermore, since I will be checking in at ORD at a UA Domestic desk, will they even have access to the LH (BOS-MUC) Emer. Exit rows?

Any help would be more than appreciated!!!

Thanks!

Alex
