Fifa confirmed on Sunday that Qatar Airways will be its "official airline" for a host of major tournaments, including the 2018 and 2022 World Cups, the latter to be hosted by the emirate.
The deal, announced via statements from both organisations, comes days ahead of Fifa's annual congress, and just weeks after football's corruption-tainted governing body announced a $369 million loss.
"Qatar Airways is an ideal partner for Fifa as we prepare for the first-ever World Cup in the Gulf region," said Fifa secretary general Fatma Samoura.
Qatar Airways boss Akbar al-Baker said Fifa was a "natural partner" for his airline.
Under the terms of the deal – unlikely to appease Fifa critics – the Gulf carrier will also sponsor the 2017 Confederations Cup, the Club World Cup, and the women's World Cup.
As well as the 2022 World Cup, Qatar is in talks with Fifa to host the 2021 Club World Cup.
The sponsorship deal, first reported last month, comes as Fifa struggles to find new sponsors since corruption scandals which ousted former Fifa president Sepp Blatter and dozens of other football officials erupted in 2015.
Sony and the airline Emirates quit as top-level sponsors after the 2014 World Cup and were not immediately replaced.
The Fifa congress takes place in Bahrain on 11 May.
