You're too close to SE not to go the rest of the way. Others have already stated numerous benefits that don't exist if you are only 75K. The one that stands out for me is that so far this year, upgrades have cleared 100% of the time. I'm flying next week to UK and the upgrade already cleared. I will cross the 80K threshold on the way over and if all goes according to plan, I will cross 100K on the way over to HKG at end of November. If for some reason that trip does not go ahead as planned, I will definitely be looking for a mileage run.
