Travel Rules 2025-01-30 ParkingNearAirports.io

Getting denied boarding can really put a damper on your travel plans. In 2023, approximately 25,000 passengers in the USA weren't allowed to board their flights, which translates to around 29 passengers per 1 million. Although this may seem like a small number, it's essential to understand the potential reasons why you might face this issue.


From not having the proper identification, such as a Real ID, to arriving at the gate too late, there are several factors that can prevent you from getting on your flight. This ultimate travel guide will explore 5 common reasons why you might be denied boarding and provide you with tips on how to avoid them. By being prepared and aware of these potential obstacles, you can help ensure a smooth and stress-free travel experience. So, let's not waste any more time and get to the point right now!

So what can keep you off your flight?

You lack a Real ID

Starting on May 7th, 2025, federal law will require all domestic travelers in the United States to have a Real ID to board flights. This requirement aims to enhance security by allowing only upgraded state-issued driver's licenses or ID cards. Many states have been issuing Real IDs for years, and they're clearly marked with a star, flag, or the word "enhanced" in the corner. Some domestic flyers might already be using a Real ID without even knowing it.


If you haven't updated your ID, now is the time to start the switch, although there'll be a grace period until 2027 for agencies and passengers to fully comply. The Department of Homeland Security (DHS) provides details on the process, which varies by state, on its website. Most travelers can receive an upgraded Real ID by visiting a local Department of Motor Vehicles (DMV). However, a passport can still be used for air travel within the United States.

You skipped the line

Waiting in line to board a plane is one of the least enjoyable parts of flying. But airlines are cracking down on line cutters. Ignoring boarding instructions and rules can cause airline staff to refuse to let you board the plane. Gate agents have the right to refuse any passenger a seat. To avoid getting sent to the back of the line or being kicked off the flight, listen to the airline's guidance.


In late 2024, American Airlines started using new technology that automatically flags passengers who board before their zone. An AA representative says, "The new technology is designed to make it easy for customers to get the benefits of priority boarding and helps improve the boarding process by giving our team better visibility into how boarding is going." If you need to board early for special reasons, like medical needs or traveling with small children, ask the gate agent before boarding starts.

Your passport has damage

Passports are essential for international travel, and even for domestic travel if they are your main form of ID. Most people know that an expired passport won't work, but a damaged one can also cause problems.


The United States Department of State warns that significant damage beyond normal wear and tear, such as torn pages, peeling laminate, or unauthorized markings, can lead to delays or being denied boarding. But what counts as normal wear and tear is unclear – it's up to the individual checking your passport, whether an immigration officer or airline employee.


Even minor wear and tear on the data page (the one with your photo and information) can cause issues. Make sure this page is in good condition before every trip. If your passport is well-used, think about getting a new one before any problems come up. A passport holder is a practical and stylish way to protect this important document – some even have a spot for an Apple AirTag to help track it if it gets lost.

You arrived late

Occasionally, we all run a bit late, but this is one of the most common reasons travelers get turned away at airports. Even a few minutes can make a big difference for airlines running on tight schedules, so it's essential to follow the check-in and boarding deadlines. Before your travel day, make sure you know exactly when to arrive at the airport and when to be at your gate.


Most airlines recommend arriving 2 hours before domestic flights and 3 hours before international flights, but this isn't the minimum requirement for check-in. For example, American Airlines requires passengers to check in at least 45 minutes before scheduled domestic departures and 90 minutes before international flights. Delta Air Lines has a slightly different policy for most American airports, requiring a minimum check-in time of 30 minutes before departure. If you try to check in later than these times, especially if you're planning to check a bag, you might be denied boarding, as there are specific time requirements to be aware of.


Even if you've checked in online, you still need to clear security and make it to your gate on time. Many airlines require passengers to be at the gate 15 minutes before departure, and if you're late, even by a few minutes, you'll likely be turned away.

You were bumped

Have you ever been tempted by an offer to take a later flight in exchange for a flight credit? Airlines sometimes do this to free up seats on an overbooked flight. If not enough passengers volunteer, some will be involuntarily denied boarding or "bumped" from the flight.


Airlines often overbook flights to account for no-shows and maximize profits. The Department of Transportation requires airlines to fully compensate these unlucky passengers, but it's still a major inconvenience. To avoid being bumped, check in online as early as possible, usually 24 hours before departure. Joining the airline's free frequent flyer program or booking a higher fare class can also make you less likely to be bumped.

Have you ever heard something about off-site parking? If not, we recommend you take a closer look at this part of the article, as this information will be handy for those who prefer to travel by air and get to the airport by their own car.


Most people suppose that parking at the airport is the fastest and most convenient option for them. However, it's not actually true. We'll explain to you why.


To be true, being in a terminal parking lot isn't convenient at all. Although on-site airport parking is the nearest place where you can leave your vehicle for the period of a trip, you can face the following difficulties:

  • You will need to find a spot in a crowded lot,
  • You will need to carry the luggage all the way through the parking lot,
  • You must pay expensive fees without great service.

Sounds not good, right? However, we found an excellent solution for you – in this case, off-site parking can become a savior for you. So if you're trying to find a parking spot with great service nearby the airport you're flying from and don't want to leave there the most significant part of your budget, pay attention to this option.

How does it work?

Obviously, people who chose a car as a way to get to the airport want to leave their vehicle safely while traveling and not to face the problems we described above. So what can off-site airport parking offer its customers?


Although a few miles usually separate such parking from the airport, you shouldn't worry about this. Off-site parking provides free shuttles going back and forth between the parking lot and the airport. Thanks to this, it removes any worries about getting stuck in traffic on the way to the airport during peak times. So all you need to do is choose the best time for you and inform the parking lot staff.


How does it work? Actually, everything is straightforward: when you come to the entrance, the staff will remove your luggage from your car and load it onto the shuttle, which will take you and your bags to the terminal. Then, the vehicle will be parked securely.


In addition, this type of parking is much cheaper, and this is good news, as nobody wants to waste money. Therefore, off-site parking is the perfect option to receive excellent service and save money at the same time.
