The tweet has since gone viral and "Sarah's" profile has been bombarded with other users lambasting her for the ill-advised message to the airline. Fair warning: the responses on her timeline feature obscenities from other users.
She has since gone on to claim her account was hacked, claimed she meant June 1st was "big" because it is her sister's birthday and, apparently a fan of the singer Demi Lovato, tweeted "I always wanted to be famous, but I meant like Demi Lovato famous, not Osama Bin Laden famous."
However, she also doesn't appear to be taking it very seriously, calling today, "the highlight of my twitter days," and tweeting, "I wish I had a time machine lol."
The moral of the story is: Don't tweet terrorist threats at an airline. It's never a good idea.
Update: Sarah has now taken to Twitter to defend herself, using screenshots of notes on her phone to explain the situation. She said she wrote the tweet as a joke a month ago, but didn't send it because it "wasn't a good idea." However, she says her Twitter "tripped" and sent the draft of the earlier tweet today unbeknownst to her. Read the explanation here:
