Qatar has twice hosted major soccer tournaments but neither was played in June or July.
The 2011 Asian Cup was played in January, the month preferred by European body UEFA and its president Michel Platini.
In 1995, Qatar staged the Under-20 World Cup in April. A spring 2022 tournament has been proposed by Karl-Heinz Rummenigge, head of the European clubs’ association.
Blatter has pushed FIFA in recent months toward moving the 2022 World Cup dates after spending two years insisting that Qatari officials first had to ask for a change.
The Qatar organizing committee insists it can stage a safe tournament in June-July by using air-cooling technology. However, Qatar says it would comply if FIFA reaches a consensus for change.
Any switch of the dates could lead to legal challenges from the losing bidders, European leagues and broadcasters that bought rights based on a June-July event.
The U.S. is FIFA’s most lucrative territory, and November or January dates would clash with the NFL season. Fox, Telemundo _ owned by NBC Universal _ and Futbol de Primera Radio agreed to pay a combined $1.2 billion in October 2011 to broadcast the 2018 and 2022 World Cups.
FIFA has ruled out compensating losing bidders after 2022 candidate Australia said it wanted to recoup its publicly funded $40.6 million campaign costs.
FIFA gets around 90 percent of its revenue from the World Cup. It earned $3.655 billion from commercial deals tied to the 2010 tournament in South Africa.
