Many thanks for all replies, lots of useful input. Unfortunately, initial departure airport not MUC, so that add-on (within Europe, I hasten to add) adds up to approx 400 EUR(!). Also, arrival/departure time CPT totally anti-social (05.30-06.25 local) - causing fairly major local probs (am sure PAX-Boy can furnish further info - not a good idea to be on the roads in this part of the world at that time of day, believe me!!) So looks like have to go with LH/LX (again!). BTW, Etihad even less helpful re UMs
