Fenerbahce's private chartered aircraft from the airline Borajet was en route from Istanbul for Thursday's Europa League game against Manchester United.
"The plane made a perfect and safe landing in Budapest at 1215 p.m....after pilots reported a loss of cabin pressure," spokesman Mihaly Hardy told Reuters.
Hardy said another plane was on its way to Budapest from Istanbul to pick up the team and fly them to Manchester later on Wednesday.
Fenerbahce said on its club Twitter account that a bird had hit the cockpit windscreen.
