Welcome, shawnrobel.

First, it appears SeatGuru says there is impaired seat pitch in 41H and J, so I would avoid them. (Seat pitch* can not be ameliorated by raising a seat arm - it is the distance, point to point, between seat rows... more pertinent to "leg room" than seat width.) I think you are basically stuck with 41 AB, at least according to SeatGuru - it's surviveable, as I have done DFW-ZRH in 13G and I am 6'4" / 193 cm (I'd have been more ocmfortable on the daytime return flight,) but I'd watch the seat assignment chart and arrive at the airport early and see if I could score an exit seat vacated by an elite flyer upgraded to J with a VIP systemwide upgrade or miles and copay, which can happen very close to departure on this popular flight.

Second, since you are new here, I will take the opportunity to point out some useful tools that can make your stay here more enjoyable and productive. Accessible via the Help Menu above right, are a New User's Guide, Guidelines and Rules, FAQs and more tools, like an Airport Code Lookup and Glossary. There is also an airline Wiki available via the Extras menu, and much more. The Search function is also a huge asset, which allows us to look for answers to questions that may have been asked before, etc. so we don't have to start new threads when those may already exist.

Cheers, and wishes for a good flight, JDiver

* Seat pitch: The distance measured between a seat back and the seat back in front of it. Actually, it can be measured from any point on a seat to the SAME point on the next row of seats. FlyerTalk Glossary.
