Do BD refund you the mile difference?
Is there any compensation involved and from whom if any? (I wouldn't fany taking my chances with TK on this though

)
This has happened me.
Recourse? Very little - you have a contract for carriage, not comfort. Talk to the rebooking team and make sure you're on the A340, which is nice enough, actually. Absolutely forget the A321/B738.
Refund? Yes. On the spot.
Compo? No.
