Qatar is offering double elite qualifying Qpoints for all the flights on Qatar Airways between November 20th and December 31st this year . The number of Qpoints one earns depends of the fare class and route. Unlike most of the other airlines, their system is not based on actual flown miles but rather regions. This probably benefits fliers on shorter routes that earn the minimum number of Qpoints and penalizes fliers on longer ones.
Apparently, there is no need to register for this offer. http://www.qatarairways.com/global/en/privilege-club-offers.page.
Here is a list of Qpoints earned between different regions and Doha.
Here are Qatar Airways different frequent flier levels, and the number of Qpoints required to qualify and to retain.
