A346s are fitted with AVOD head-to-toe are currently in service HOWEVER the airline is notorious for aircraft swaps which can be annoying as some of their international fleet have no IFE in economy. The aircrafts to watch out for are the A330-300s, B747 All Series and some 777-200s. I believe TG
has or is in the process of providing economy passengers on the old A330-300s with content loaded tablets.
I have had my aircraft swapped more often than not (except on the (now ceased) LAX
non-stop services with the A345).
If you are Star Alliance Gold and flying economy, BKK
would be a better transit option as you have shower access which is not the case in SIN
where you will have access to the KrisFlyer Gold Lounge.
If I were you I'd fly SQ
all the way if possible as I am not fond of LH
however this shouldn't be an issue as the SIN
is a red-eye service and I would pick this option if I wasn't too fussed about taking a shower during transit
