Turkish Airlines har lavet deres egen challenge, hvor man kan få en miles ved at flyve til de seks forskellige kontinenter, som de flyver til. https://www.turkishairlines.com/en-...fly-across-6-continents-Earn-1-million-miles/
That was concluded now for registrations and booking of tickets. So only tickets booked until July 7 (i believe) will be considered for the challenge.
