343 on VS001 & VS002 Routes

Hi all,
I noticed that for the last few days a 343 has been running on the VS001 and VS002 routes, and I just wondered if anyone had any info regarding on-going plans? Or is it just because of light-loads, do you think? I'm flying this route in UC in Feb, and it's still showing as a 346 in my booking - I'm hoping it stays that way, or at least goes to a 744, but a 343 would be a bit of a shame for my next UC trip! Or can anyone cheer me up about UC in a 343??
Thanks!
