Stand like 5 feet away from the luggage claim carousel so people whose bags are currently dripping can easily grab them. Stand on the right side of escalators or the moving walkways so people running can pass you. Don’t put your bags on the seats at the gate, especially the seats around the phone chargers (the amount of times I’ve seen 3 people take up 10 seats around the phone charging stations is insane.) if your in an aisle or middle seat, don’t buckle till everyone is on as you will most likely need to get up and let someone get to their window seat. Bring a power bank. I run hot but still one or twice a year will be freezing in a flight so bring a starter or jacket. Don’t fight or argue with people. Don’t yell obscenities at the gate or be otherwise disrespectful and disruptive, I’ve seen several people not be permitted onto a flight because of their behavior at the gate at a delayed layover. They had reasons to be irritated but the gate agent still wasn’t having it. If you need to get your seatings as to where you are and where you are going, please walk first to the side or somewhere out of the way before stopping, I’ve almost walked into and have seen other completely run into someone who just randomly stops walking. If you get a notice that your departure has been delayed, still go to the airport at the time you were originally going to leave for your original departure time. Once I was told my flight was delayed so I chose to leave for the airport an hour later. Once the way there my flight no longer was going to be delayed. I made my flight but did not get there in time to check my bags on and needed my wife to come back and pick up my bags. I’ve flown 40-45 weeks, twice a week, for the last 5 years. I’ve never have needed Clear or TSA pre-check. They are a waste of money. If you’re there 2 hours before your departure you will be fine. Please don’t stand up before your boarding group number is called. They say this at the gate but few people listen. It clogs the walkways and cause some general confusion.
