To ensure a smooth journey, absolute information security and avoid falling into the trap of hidden costs, passengers need to pay special attention and apply some of the following "hard-won" experiences.

Be careful in protecting personal information

Personal information security is the first key factor that every passenger needs to pay attention to when making online transactions. Currently, there are many fake websites and applications appearing, taking advantage of buyers' psychology of hunting for bargains to advertise cheap tickets regardless of the price, with the aim of stealing user information.

Booking airline tickets through the application has become a top priority for some travelers, because of its convenience and sometimes the application will have promotions, helping passengers buy tickets at extremely affordable prices.

To avoid this risk, passengers need to strictly follow the rules. Always check the authenticity of applications and websites. Only download applications from official stores such as App Store or CH Play (Google Play). For websites, carefully check the website address (URL) and make sure it has a security symbol (HTTPS) before entering any personal information or making payments. Transactions through official applications of airlines or long-standing reputable agents will significantly reduce the risk of fraud.

Although convenient, it still contains many risks regarding information security and certain limitations, causing many passengers to worry.

Visitors should be careful not to reveal their personal information.

During the booking and payment process, always be alert to sophisticated forms of fraud. Never share your OTP (one-time password) code with anyone. At the same time, be highly alert to fraudulent forms of email, text messages or suspicious calls impersonating airlines or ticket agents. Never transfer money to personal accounts provided via text messages or social networks.

Check the ticket information carefully.

After ensuring the safety of the application source and device, passengers need to focus on carefully checking the information related to the ticket to avoid errors that lead to unfair fees or even being denied boarding.

To ensure the safety of personal information and bank accounts, passengers should make transactions on personal electronic devices such as phones, laptops, tablets and avoid using public devices to book airline tickets.

Passengers need to carefully check their information, this is an extremely important step. Passengers need to carefully check the information when registering to buy airline tickets, including Full name (must match the ID card), CCCD/Passport number, Email address and Contact phone number. A small mistake in the name can lead to having to pay a very high name change fee or not being able to fly, causing unnecessary trouble.

In addition, passengers should also note that when booking flight tickets, do not share the OTP code with anyone.

When making a payment, airline or agency apps tend to automatically add default services such as travel insurance or priority seat selection. Passengers must carefully check and uncheck these services if they do not need them to avoid being charged unreasonable extra fees, leading to "losing money". This is one of the most common "hidden cost traps" when booking tickets via apps.

Each airline has its own strict regulations on service. To avoid being passive or having to pay unnecessary extra money at the airport (which is often much more expensive), passengers need to clearly understand the regulations on baggage, including the maximum weight and size for carry-on and checked baggage. If needed, passengers should buy extra checked baggage right on the application when booking tickets, because the price to buy in advance is often much cheaper than buying at the airport check-in counter.

Always have a backup plan

A smooth journey depends not only on successful ticket booking but also on proactively understanding the conditions of the purchased ticket. Passengers need to clearly understand the conditions of the ticket they buy, especially the refund and exchange policy in case of schedule changes. Cheap tickets (promotional tickets) often have extremely strict conditions, may not allow refunds, exchanges or have very high exchange fees. Understanding these conditions will help passengers be more proactive in arranging plans and making decisions to buy tickets that suit their flexible needs.

Each airline will have its own regulations on service. To avoid being passive or incurring unnecessary extra costs, passengers need to clearly understand the regulations on baggage.

After successful payment, make sure you have received a confirmation email from the airline or agent. This is the most important proof to confirm the transaction. Always save the Booking Reference for easy searching, online ticket management and check-in procedures later.

Complying with the above notes not only helps passengers save costs and avoid hidden price "traps", but also ensures absolute information security, providing a convenient ticket booking experience and a truly smooth and complete flight.
