The Federal Aviation Administration wants to fine an airline passenger more than $52,000.
This is after it says the passenger tried to get into the cockpit of a Delta flight that was leaving Honolulu for Seattle in December.
The FAA says the passenger assaulted a flight attendant in the process.
The administration launched a zero-tolerance policy against unruly behavior in January.
And the agency has received 1,300 reports and has fined 17 passengers.
The policy comes as more people head back to airports.
Monday, the Transportation Security Agency says it screened 1.85 million passengers Sunday - the highest number since the start of the pandemic.
