I have a question:

I've been taking a number of Thai Airways flights sold on TG's website complete with TG flight numbers. I am not booking through Thai Smile's site, I'm paying a slightly higher fare and the flight shows as a TG flight number. However, the flights are ultimately operated as a codeshare by Thai Smile.

When I book, it's shown as if I'm booking on a TG flight in W class, but when I check in, the flight number on the boarding pass is that of Smile's WE with the TG flight number listed underneath.

Do these flights credit?

WE flights don't credit, but if it's sold as a TG in W class, shouldn't this accrue miles?

I haven't gotten any credit for any of these flights, and am wondering what's up with this.

Thanks.
