You are looking at a flight over a month from now and counting on J space? Being an E50k at that...(not knocking on the status itself but you do realize that chances are you will be waitlisted, behind all the SEs, the E75ks and the E50s with higher fare.

I remembered seeing the waitilist once for YVR-NRT and there were over 25-30 ppl on the list for 2 available seats...
