ET: DUB-CPT €1,400 in March 2018
I'm seeing some great Ethiopian Airlines fares for early next year from Europe to Cape Town - I have booked DUB-ADD-CPT round trip for €1,400.05 from the (wobbly) ET Website with transfers of +/- 2 hours at ADD. They use 787s with conventional 2-2-2 seating, apparently similar to LH's A380 seating.
Note that this price books into P class with miles only in ET's FF scheme. Other *A plans earn zero.
D fares are available from some OTAs at a couple of hundred more Euros.
