In January I did the Qualiflyer promo mileage run : Five times BSL-BRN in C-class for € 705 all-in. As a result Qualiflyer credited 301,500 award miles to my account (€ 0.0023 per award mile).
Recently I flew Europe - Hawaii in First for 165,000 Qualiflyer miles return, i.e. at a cost of € 443 tax included. I found ZRH - LAX on Swiss in First already worth it. Excellent service! Compared to Swiss the segment LAX - Hawaii on AA was a nightmare : flight attendants not only ugly and outdated as on most US carriers, but more annoyingly AA staff provided bad service.
