As I had registered with Emirates skyward I was overwhelmed that one day I would be able to win a free ticket to some place. I had searched many cities and tried to find out that how many miles were required to win a flight ticket from delhi to that particular city. I was excited assuming that soon I would fly from Delhi to Jeddah with no cost. At that time the system showed me that 17500 miles were required to book a flight free of cost from Delhi to Jeddah. When I got 19000 miles it showed that 27500 miles are needed. But when I reached to 27500 now it shows that 60000miles plus 12000 INR required to book a flight ticket from Delhi to Jeddah. So I think that they are just befooling people to sell their tickets.
