Should have posted this before, as the booking was made quite a few days ago:
EDI-ZRH Y (BD)
Cash & Miles
3,375 miles, GBP56.80 cash, taxes & CC fee.
Really a good deal, I thought, for early January when prices with other carriers, particularly so called Low Cost carriers, are sky high.
In an interesting bit of maths, if I had booked this with M&M (as a One Way European business class tkt) it would have cost 33,750 miles, so 10 times more miles. (M&M have no Cash & Miles option, though).
This was booked online, as it is solely on BD. However, if I wanted to add a sector, would that be possible at this stage? Presumably through the call centre before ticketing? But how does End-on-End work, where you can add sectors to the beginning and end of a trip? That is something I still have not yet got into...
