Airports are busy places, with hundreds of thousands of people passing through each day. Many travellers want to stay connected while they wait for their flights, so it's no surprise that most airports around the world offer free Wi-Fi. However, not all airports provide this service, and there can be significant variations in speed and safety. While some airports offer supersonic Wi-Fi, others provide limited access or none at all. This can be due to local laws, security concerns, or revenue streams from SIM card sales. Additionally, travellers should be cautious when using public Wi-Fi due to the risk of hacking and identity theft.

What You'll Learn
Airports with the fastest free Wi-Fi
While most airports around the world provide free Wi-Fi to travellers, not all airports offer the same quality of service. According to Ookla's list of airports with the fastest free Wi-Fi in the world during Q1 2022, four US airports topped the list.
San Francisco International Airport had a median download speed of 176.25 Mbps during Q1 2022, followed by Seattle-Tacoma International Airport, Dallas/Fort Worth International Airport, and Chicago O'Hare International Airport. Hartsfield-Jackson Atlanta, Los Angeles International, and Denver International were also part of the top ten airports with the fastest free Wi-Fi globally. Dubai International Airport, Amsterdam Airport Schiphol, and Charles de Gaulle Airport in France completed the top ten list.
Outside the US, Wi-Fi speeds at airport lounges varied dramatically. While Wi-Fi in airport lounges was often faster than free airport Wi-Fi, this was not always the case. Patrons of airport lounges are also paying for the privilege, whether by the day or the year, so their expectations are higher.
It is important to note that airport Wi-Fi (and all unsecured networks) present serious risks to your digital safety. Hackers can spy on you and intercept data you send over a compromised network, potentially leading to identity theft, account takeovers, and financial losses. To protect yourself, you can use a VPN (virtual private network), enable two-factor authentication, and only visit sites with an HTTPS address.

Cybersecurity risks of airport Wi-Fi
Many airports around the world provide free Wi-Fi services to travellers. However, airport Wi-Fi (and all unsecured networks) present serious risks to digital safety. Here are some of the biggest cybersecurity risks of airport Wi-Fi:
Identity Theft and Account Takeovers
Hackers can spy on users and intercept data sent over a compromised network. This means that any information entered, such as passwords or Social Security numbers, could be used to steal identities or break into online accounts.
Financial Loss from Stolen Bank or Credit Card Information
Unsecured Wi-Fi may allow cybercriminals to steal financial information, such as bank account numbers or credit card details.
Business Email Compromise (BEC)
Cybercriminals often target business travellers and try to access their email accounts to conduct fraud.
Phishing Attacks Using Spoofed Websites
Attackers inject phishing sites, fake websites, or fraudulent login pages to trick users into giving up personal data.
Malware Infections from Compromised Downloads
Users may be asked to download illegitimate apps or files to access airport Wi-Fi. These fake downloads hide malware that gives hackers access to devices and data.
Packet Sniffing Attacks
Hackers can steal "packets" of data over unsecured Wi-Fi networks and use custom software to extract individual pieces of data, including passwords and credit card information.
Malicious Pop-Ups
Attackers insert pop-ups into legitimate airport web pages and services. Clicking on these pop-ups can download malware onto a device or direct it to a fake website that steals personal information.
To protect against these risks, travellers can use a VPN, enable two-factor authentication, keep devices and software up-to-date, and avoid sharing sensitive information over unsecured networks.

How to protect yourself on airport Wi-Fi
Airport Wi-Fi is a convenient way to stay connected while travelling, but it's important to take precautions to protect yourself from potential risks. Here are some ways to safeguard your personal information and digital devices when using airport Wi-Fi:
Be Wary of Registration Processes
Many airports offering free Wi-Fi require new users to register before accessing the internet. While this is usually a straightforward process, some networks ask for more data than others, and it's often unclear how this data is protected. To reduce the risk of exposing your personal information, avoid entering your actual details. Instead, use an email alias to shield your primary inbox from potential scammers and hackers.
Verify the Wi-Fi Network's Authenticity
Hackers often create "evil twin" networks with names similar to the airport's legitimate free network. These fake networks trick users into connecting, allowing hackers to access uploaded or downloaded files. Before joining a Wi-Fi network, always double-check its name to ensure it belongs to the airport. Be cautious of networks requiring registration or asking for excessive personal information.
Enable a Virtual Private Network (VPN)
A VPN provides a secure and private connection within the wider internet. When you access data through a VPN on public Wi-Fi, it helps protect your data from interception and keeps your network secure. This adds an extra layer of protection to your online activities, making it harder for hackers to access your information.
Turn Off File and Printer Sharing
If you typically have file and printer sharing options turned on for trusted networks, remember to disable these features when using airport Wi-Fi. Turning them off ensures that no unauthorized individuals can access, download, or print your personal files while you're connected to a public network.
Beware of Suspicious Pop-ups and Websites
Attackers may inject pop-ups or create fake websites to trick users into downloading malware or giving up personal data. Be cautious of prompts asking you to sign up for additional features, install browser extensions, or download software. Unless you're certain it's from a safe source, avoid interacting with these pop-ups. Always look for secure connections, indicated by a locked padlock icon in your browser's URL bar.
Use Two-Factor Authentication
Enable two-factor authentication for added security. This means that even if a hacker has your password, they won't have access to your phone, making it much harder for them to log in to your accounts.
Remember, airport Wi-Fi, like any unsecured public network, poses risks to your digital safety. By following these steps and staying vigilant, you can significantly reduce the chances of becoming a victim of cybercrime while enjoying the convenience of airport Wi-Fi.

How to get Wi-Fi without a local number
Many airports around the world offer free Wi-Fi services to travellers. However, some airports, particularly in India, require a local phone number to access the Wi-Fi. This can be frustrating for tourists who don't have a local SIM card or number. Here are some ways to get Wi-Fi without a local number:
Use a VPN
A Virtual Private Network (VPN) is a secure and private solution that allows you to send and receive data while maintaining the privacy of a private network. By using a VPN, you can protect your data from interception and reduce the risk of network compromise when using public Wi-Fi.
Two-Factor Authentication
You can enable two-factor authentication for your online accounts. This means that even if a hacker has your password, they won't have your phone, making it much harder for them to access your account.
Use an Email Alias
If you are required to enter an email address to access the Wi-Fi, use an email alias to shield your primary inbox from potential scammers and hackers.
Use an International Number
In some cases, travellers have reported success in using their international phone number to access airport Wi-Fi. It may be worth trying your international number if you have one.
Visit Airport Lounges
Some airport lounges provide preset IDs and passwords for their Wi-Fi networks. You may need to access the lounge to obtain this information, so it is recommended to ask beforehand.
Use a Boingo Account
If you have a Boingo account, you may be able to use their networks available in some international lounges to access the internet without a local number.
Use a Different Airport
Some airports, such as Zurich Airport in Switzerland, offer Wi-Fi access by scanning your boarding pass. This can be a simple way to get online without needing a local number.
It is important to note that airport Wi-Fi and unsecured networks can present serious risks to your digital safety. Be cautious when entering personal information and consider using a VPN or other security measures to protect your data.

Wi-Fi options when the airport network is crowded
Many airports offer free Wi-Fi, but the strength and stability of the signal can vary depending on various factors, including the number of people using the network. When an airport network is crowded, you may experience slower speeds and unreliable connections. Here are some options to consider for a better Wi-Fi experience in such situations:
- Use a wired internet connection: If available, opt for a wired internet connection, typically found in airport lounge areas. These tend to be less crowded and provide a more stable connection for your devices.
- Visit an airport lounge: Airport lounges often have dedicated networks with faster speeds and more reliable connections. Access to these networks is usually included with lounge entry, which you can obtain through memberships, premium tickets, day passes, or eligible loyalty programs.
- Use a Virtual Private Network (VPN): A VPN allows you to connect to the internet through a secure and private network. It helps protect your data from interception and reduces the risk of network compromise.
- Turn off automatic Wi-Fi connections: Disable the "Connect Automatically" feature on your device when in busy airport environments. This prevents your device from connecting to unsecured networks without your knowledge.
- Use a local SIM card: Local SIM cards can provide a more reliable and faster connection than airport Wi-Fi. However, this option may be less convenient for short trips due to the need for activation and potential compatibility issues.
- International roaming: If you're travelling internationally, consider using international roaming instead of airport Wi-Fi. It often provides a more reliable, fast, and secure connection from the moment you land.
- Use public DNS servers: Using public DNS servers instead of the Wi-Fi network's built-in DNS can sometimes help reduce lag and improve your connection speed.
While these options can enhance your Wi-Fi experience in crowded airport networks, it's important to remember that airport Wi-Fi security risks still exist. Be cautious when entering sensitive information and consider using additional security measures, such as two-factor authentication, to protect your data.
