Codeshare on MH Seat Assignment
 

I am on a Turkish ticket in J that connects to an MH Codeshare and I am unable to get advance seat assignments. Is there any way around this? Malaysian Chat said I had to wait until KL and go to the transfer desk.

Advance seat selection isn't possible for such codeshares.

An off topic observation to share that I thought might be useful if this thread comes up on a Google search in the future...

Qatar allows for exit row seat selection for OWE at time of booking while MAS only allows at check-in time.

I was looking at Qatar operated, but MAS codeshare ticketed flights and was unsure which policy would apply...and always a major consideration...what the system actually allows you to do.

Surprisingly, I was able to select exit row/ extra leg room seats for free on the MAS website for the QR operated flights.
