This is my first year with status (and I made 1P!). I am enjoying E+, particularly exit rows on the aisle. I really don't like window seats as it is a little claustrophobic on a full flight, but I've been very lucky with no "neighbors" in the Exit Row on several recent flights.

I am now flying SFO-YVR on A319, with 11D (exit) reserved on each flight. However, reading past threads, I think this is a good opportunity to burn some certs. and upgrade. However, I have often felt really uncomfortable in a window seat especially up front where it seems bumpier to me during turbulence (as opposed to over the wing area).

Is there anyway to state an aisle preference or am I stuck with the window if that is what they assign me? I haven't walked through the online upgrade request to find out if there is a request in there because I wasn't sure if you pull the trigger before you get to that point (if it exists at all). If not, is this something that could be noted in a phone call?

Pardon my ignorance, and thanks in advance!
