Sources familiar with the investigation say the flight attendant accidentally bumped some passengers, A man then got up, walked to the galley and struck her.

“There was a doctor on the flight luckily, he said it wasn’t broken, but she was bleeding, so they took her to the hospital,” Another passenger said.

Nelson says 85% of all altercations this year are related to masks, but the second-highest factor is alcohol.

They would like to-go alcohol at airports to end and see more serious consequences for anyone who disrupts their work.

“We need DOJ criminal enforcement make we need to make the FAA’s zero-tolerance policy permanent,” Nelson said.

The latest assault sent the flight attendant to a Denver hospital, yet another example of what Nelson says is getting increasingly violent and has become far too common.

“We simply cannot accept this as the new normal,” Nelson said.

It’s unclear if alcohol or any substance was a factor in the altercation on American Airlines Wednesday night.
