Haven't a clue about yields but the loads for August 2012 were:
LIS - 86%
PRG - 91%
BUD - 92%
Obviously peak season but generally I believe the loads were pretty good. The problem is finding the right airline.
CSA have tried BHX-PRG before and pulled out and they seem to be shrinking all the time. Wizz would be the obvious choice for both PRG and BUD if it weren't for their LTN base. As for LIS, BHX didn't appear in Ryanairs proposed new base which would leave us with TAP; they're MAN route seems to be doing well, the fly LGW too which means they look to places other than LHR and as a member of Star Alliance their could be some back up there.
Having said all that, I think all three routes could work well for MON; LIS and PRG would definitely have been a better bet than MUC.
