I need to fly from CPH to PRG and then PRG to BRU
I can have 2 stop overs, PRG & BRU but I dont need or have time for a 3rd leg, can I just throw the 3rd coupon away?

I am flying across the pond into CPH and out of BRU on UA.

I have looked at LCC between CPH & PRG and can get my flight on Sterling for about $42 (dont cae about miles for that price) but cant find a LCC between PRG & BRU

Czech Air is $ 686
and
SN is $ 650

for this leg - so any thoughts greatfully accepted
