An observation: I searched one way australia to doh for 1 person, cost 100K avios, but when i changed to 2 persons (same dates), cost not 200K but 400K avios (flexible award). So it seemed one has to fly one day and another on a different day (next day or previous day).
Q: can i use my avios to book QR award flights for someone else? Most airlines would allow this, so hope QR would do the same. Thanks for confirming this.
