FIFA's ethics committee has cleared president Gianni Infantino of misconduct and said it had concluded its investigation into possible ethics breaches.
Infantino was being probed for his use of private flights and other possible ethic code infringements, but investigators said they found no violations.
The 46-year-old Swiss was in February elected president of the scandal-hit ruling football body.
The investigation looked into flights to 2018 World Cup hosts Russia and 2022 hosts Qatar in which Infantino reportedly travelled in private jets paid for by Russia's Sports Minister Vitaly Mutko and from energy giant and FIFA sponsor Gazprom.
It is thought a mitigating factor in the investigation was that the method of travel was the only way the FIFA president could fulfil a tight schedule that featured several important meetings.
Investigators are also thought to have looked into a flight to visit Pope Francis at the Vatican which was paid for by a Russia businessman who, however, has no links to football.
Preliminary investigations had focused on potential breaches of ethics codes concerning general rules of conduct, loyalty, conflicts of interest and the offering and accepting of gifts.
Formal investigations were then opened on possible code violations regarding Infantino's flights taken during the first months of his presidency, hiring processes and a refusal by Infantino to sign a contract specifying his employment relationship with FIFA.
However, the investigatory chamber "found that no violation" of the FIFA code of ethics had been committed by Infantino.
The adjudicatory chamber had accepted the decision, a statement said.
The investigation concluded there were no code breaches relating to the flights taken by Infantino and there were "no relevant situations involving conflicts of interest" concerning his position as president.
Benefits "enjoyed by Mr Infantino were not considered improper in the light of applicable FIFA rules and regulations".
Investigatory chamber member Vanessa Allard, who led the investigation, found that hiring processes and the contract issue were "internal compliance issues rather than an ethical matter".
Infantino welcomed the decision and "would like to thank all those who co-operated with the Ethics Committee to ensure that the facts were heard and the truth prevailed," a FIFA statement said.
Infantino had last month dismissed claims of personal financial gain as FIFA president, saying he had paid for all of his personal outgoings and "have always adhered to ethical principles in my professional life".
That had followed media reports at the time that FIFA had paid his personal expenses and that he had allowed himself to be flown in a private jet paid for by a Russian oligarch.
Infantino had dismissed reports which said he had rejected a proposed salary, saying the issue was never about the amount but "how the process was managed".
In May Domenico Scala, FIFA's former independent audit and compliance chairman, who was responsible for determining Infantino's salary, resigned in protest at a FIFA congress decision he said "undermines" reforms at football's governing body.
Infantino was elected FIFA president on February 26, formally ending the 18-year reign of fellow Swiss Joseph Blatter, on a mandate to restore credibility amid continuing US and Swiss corruption probes.
FIFA's statement following the ethics committee ruling, said: "With this matter now resolved, the President and the FIFA administration will continue to focus on developing football as well as their efforts to improve the organisation.
"Tangible progress has been made in key areas such as ensuring that those who have acted against the interests of football are identified and held to account, improving FIFA's governance and repairing its reputation, and restoring trust with its stakeholders. This critical work will continue."
