I am looking at flying HND-DOH-ZRH with QR and paying with Avios.
Booking it online shows 112500 avios + 41.60 CHF. If I look at the legs separately it is the same Avios but 29.60CHF + 125.70CHF in taxes.
If I call BA and try to book it with a 26h stopover, will I get the same taxes as for only 2h stop, or will it be the sum of the parts?
