I've never done this before, and I'd like to
hear from anyone who has.

I'm getting an award ticket city a -> b-> c
-> a . I wish to de-plane at city c and throw
away the segment to city a. Different flight
numbers between city c and a and flight departs 12 hours later to city a.

The thing is, I will have check-in bags that I have to retrieve at city c. I assume that
I will have diff flight coupons for all segments, so that when I check in at city b, I only present the coupon for city c, and pick up my bags .

Any problems with this ?
