"Boarding lice" aside, airline passengers are now debating the latest travel annoyance that occurs on actual planes: "aisle lice."
Gate lice made headlines after American Airlines announced it was rolling out new technology that beeps when the phenomenon is encountered at more than 100 airports.
The term "boarding lice" refers to passengers who jump in line to board a flight early. "Aisle lice," on the other hand, is when passengers push their way past others in an attempt to get off the plane before everyone else.
Everyday behavior of airline passengers is a red flag to TSA and could leave you stranded at the airport
On the "r/delta" Reddit forum, one flyer asked: "Who's more annoying? Door lice or aisle lice?"
The user shared that he or she was on a flight from Minneapolis-Saint Paul International Airport to LaGuardia Airport and witnessed "aisle lice" as soon as the plane landed.

"Not only did the two people next to me decide to stand up, but (somehow) the guy in the window seat pushed forward and became the first of all of us to get off the plane," the user wrote.
Fox News Digital reached out to Delta for comment.
The passenger ended up going to the airport terminal restroom, the user added.
The mysterious 'ding' you hear on a plane may not mean what you think
Flyers shared their thoughts in the comments section.
One user posted: "Aisle lice. Door lice don't bother me because most people want to go to the bin first."
A post on social media prompted users to weigh up whether "door lice" or "aisle lice" are more difficult to deal with when traveling. (iStock)
Another commented: "Aisle ticks don't bother me much because if they stand up in my row (I'm a window seat person) I usually have more room to stretch out while waiting."
"In my opinion, the aisle lice situation is much worse. Who really cares who gets on the plane first, everyone is going to get on the plane anyway. Aisle lice will slow things down, delay passengers and cause more headaches," one person said.
One user said: "Lice are lice."

"The fact that we have to choose between these two is ridiculous. Neither is a symbol of appropriate adult behavior," one commented.
Adding, "Yes, of course, there are exceptions. But, virtually everyone does it - watch your next flight. No one is exempt."

Brandon Blewett, the Texas-based author of "How to Avoid Strangers on a Plane," told Fox News Digital that "aisle lice," also known as "people who are eager to exit," .
"(Aisle lice) are those passengers who treat getting off the plane like an Olympic sport. As soon as the seat belt sign goes off, they jump out of their seats and throw their luggage down the aisle as if they're vying for prime spot," said Bleiway Te told Fox News Digital.

He added, "They recounted their travel woes in a self-righteous manner usually reserved for royals, while squeezing through rows of patiently waiting passengers in a frantic bid to save precious seconds."
"This seems to stem from a mistaken belief that being first in line somehow grants you a magical pass, bypassing everyone else and getting off the plane in an orderly manner. Spoiler alert: this is not the case, "Blevit said.

He said it was what he considered the "most annoying" travel habit because it disrupted deplaning and caused delays.
For those in a hurry, it's sometimes understandable if their connecting window is short, Bluett said.

He said flight staff should be made aware of this in such situations, and crew members would often politely ask passengers to stay in their seats and let others leave first.
"Frankly, if we stuck to the unspoken rule of waiting our turn, everyone would get off the bus faster,” Blewitt said.
