TOP ICELANDAIR TICKET CHANGE SECRETS

I just Qatar Airways Australia customer service booked a five working day, six night time stopover on a 1-way ticket. I’m flying from Boston to Bergen, Norway to join a tour team. I can get off in Reyjavik and afterwards go on to Bergen. The tour ends in Helsinki so I couldnt book Roundtrip, And that i wasnt required to. Refundable and Non-Refun
