I do not understand why so many people blame ET for not honoring these fares. of cause they did downgrade in the past but they also did honour. in 2017 there was a special sale from OSL to various places in Africa for around 600€ which was honoured.we flew to cpt with return from JNB w.o. problems and around 20000 miles with M&M. Some guessed that the norwegian consumer protection made them honour that. Anyway, I did not book this one but wish everyone good luck who did book
