A man was arrested after an alleged airport bomb threat was posted on a social networking site, police said.
Paul Chambers, 26, was reportedly due to fly from Robin Hood Airport in Doncaster more than a week after snow forced the closure of a runway.
He was arrested on suspicion of communicating a bomb hoax after a post on Twitter about blowing up the airport was reported to police.
Police said a Doncaster man, in his 20s, had been released on bail.
A spokeswoman said he had been arrested on 13 January under the Criminal Law Act 1977.
She added: "The arrest relates to alleged threats about Robin Hood Airport discovered on a social networking website.
"The man, in his 20s, is now on police bail pending further inquiries.
"South Yorkshire Police advises members of the public to use such sites appropriately, as they are easily accessible to the public and any inappropriate use could cause unnecessary concern and lead to comments being reported to police."
Mike Morton, Robin Hood Airport director, said: "The safety of our passengers and staff is of the highest importance to us and we work closely with South Yorkshire Police to make sure that any kind of unacceptable behaviour is dealt with immediately. We simply will not tolerate such activity.
"Thankfully, instances like the ones highlighted here are rare and the majority of our passengers act in a responsible way and enjoy flying in and out of the airport without any problems."
