My last RLC flight was last October (2018) to/from LHR/AMS and my previous experience was about two years ago.
I did feel slight improvement, however, but I think it was mostly owing to my ageing looked older than two year ago (and this time I used laptop worked on some Word/Excel files for a while, so maybe the crew though I was legit business traveller. )

I personally and my family as well all had experiences making us feel that EVA RLC crew have preferential treatments towards middle-age male passengers. But as I grow older, maybe it's now my prime time to really enjoy RLC experience. LOL

The pajama sizes have always been an issue, and I do highly suspect there are some understocking issue for certain sizes. I am 6'1" Asian and I couldn't fit L from the last design.

I will have two roundtrip long hauls coming up. (ORD & CDG). Will see how they do on these flights these time. Finger crossed.
