Thank you both for your helpful comments. I had to choose between AC/Swiss(from a third party company), Swiss and Lufthansa with LH being the most expensive. I ended up booking yesterday directly with Lufthansa. Changed my dates a bit and found a better deal than the original one. A lot less stressful booking directly than via third-party I must say :-)
