Passengers are permitted to reschedule Qatar flight tickets up to 3 hours before the actual scheduled departure of the flight time. If passengers don’t want to pay change charges then, they need to change the flight date within 24 hours of the flight ticket purchase. If the new flight ticket fare is less than the current flight fare then, the rest of the amount will automatically convert into the travel points which will use for the next flight ticket booking.
