AirOli quoted:
Every award ticket can include up to 8 segments. Sergio asked:
And how many stopovers? Every award ticket, even non-Qualiflyer?
You can interrupt your round trip flight once - either on the outward or return flight. The final destination and changing flights within 24 hours does not count as a stopover. In general bear in mind that if you would like to fly more than once to the same destination you need a second ticket (“Side trip rule”).
Free Tickets are available for travel on all Qualiflyer airlines and Qualiflyer Partner airlines. Flights on Qualiflyer airlines (including Turkish Airlines and PGA-Portugália Airlines) can be combined with flights on American Airlines, Finnair, Ukraine International Airlines and South African Airways.
