Being late to the airport due to inadequate time estimation, causing inconvenience to others, and occupying space... are things travelers should absolutely avoid.
Arriving late: When preparing for the airport, you can't just think about the boarding time, but also calculate the time for procedures and baggage check-in before the airline's designated time. In addition, security checks can consume a lot of time if you have to wait in line for too long. Estimate enough time for all these procedures to avoid missing your flight.
Repacking luggage: Nothing is more annoying than having to wait for a passenger to unpack their luggage to repack it because it's overweight, causing congestion in the long line. Avoiding this incident is very simple, you just need to weigh your luggage before going to the airport.

Stuffing coats into the cabin for luggage: The overhead compartment is only for luggage. If you still try to cram thick coats in there, it will take up a lot of space, and other passengers may not have enough room for their belongings.
Taking too much time at security checks: You should be familiar with regulations such as removing shoes, belts, watches, and coats, not carrying large liquid bottles in carry-on luggage, placing laptops separately on the tray... Forgetting these things will hinder and waste your own and others' time.

Preventing escalator congestion: Traveling by air often involves many last-minute changes. That's why airports are always full of people rushing from one gate to another to catch their connecting flights. If you see someone rushing down the escalator, step aside to let them pass, don't let your luggage obstruct their path.
Placing luggage on seats: Many people occupy seats in the airport lounge by placing their luggage on the seat next to them. This prevents others from having a place to sit.
Not using headphones: Listening to music at the airport without using headphones, or playing it at excessively loud volumes, can be irritating to others. Everyone here is tired, hungry, and just wants to quickly get home or to their destination. Respect them.
Treating airport restrooms like your own: Some people are overly meticulous about appearance and often leave makeup items scattered on the sink in the restroom. Respect public spaces and give way to others.

Hogging power outlets: Power outlets at the airport are often limited, so use them to charge your device and give up the plug for others. You can also use your laptop to charge your phone via the laptop's USB port.
Occupying space: Some people spread out their clothes or roll them up to make a pillow and sleep right at the entrance/exit. This not only causes chaos but also obstructs the space of others.
Causing disruption during boarding: If you don't have a first-class ticket or aren't in the first boarding groups, don't try to take someone else's spot when the flight attendants start checking tickets. Airlines often have reasons for dividing passengers into boarding groups to avoid chaos. Check the number on your ticket and patiently wait for your turn.
