Student IDs are not accepted for those 18 and older
It is important to note that the rules regarding acceptable forms of identification at airports vary across different countries and regions. In the United States, the Transportation Security Administration (TSA) has specific guidelines. While children under the age of 18 are generally not required to provide identification when travelling within the country, those 18 and older must show valid identification at the airport checkpoint.
It is worth mentioning that some airlines and countries may have different requirements for identification. For example, when travelling internationally, a passport is always mandatory, regardless of age. Additionally, some airlines may have specific rules regarding children and identification. Therefore, it is essential to check with the relevant authorities and airlines before travelling to ensure you have the necessary documentation.
In the case of not having a valid form of identification, there are a few alternative options to consider. Firstly, it is worth checking with the TSA, as they may be able to verify your identity through other means, such as additional screening or identity verification processes. Secondly, some other forms of identification, such as a checkbook or library card, may be accepted in certain cases, although these are not guaranteed.
In summary, while student IDs can be useful for various purposes, they are not accepted as a valid form of identification for adults aged 18 and older at TSA checkpoints in the United States. It is important to be prepared and carry the necessary documentation to avoid any issues during travel.

Children under 18 don't need to show ID
It's important to note that ID requirements for air travel can vary depending on the country and specific airline policies, so it's always a good idea to check with the relevant authorities and carriers before travelling. Now, regarding children under 18 not needing to show ID, here are some key points to consider:
Firstly, in the United States, the Transportation Security Administration (TSA) does not require children under 18 to provide identification when travelling within the country. A valid boarding pass is sufficient for them to pass through TSA security checkpoints. However, it's worth noting that unaccompanied minors who are eligible for TSA PreCheck must show acceptable ID to receive expedited screening. Additionally, while TSA does not routinely require ID for children, airlines have their own rules. Some airlines may request a birth certificate or government-issued photo ID for children, especially if they are travelling as a lap child. Therefore, it's recommended to check with the specific airline before assuming that no ID is needed.
Secondly, when it comes to international travel, the requirements can differ. While a passport is typically required for adults, minors under 18 may not always need one. However, it's important to remember that even infants travelling internationally will need a passport to enter or exit a country. Additionally, if the destination requires a travel visa, the child will also need to apply for one. Obtaining these documents can take time, so it's advisable to plan ahead and allow for any necessary applications or expediting processes.
Furthermore, it's worth noting that some countries or airlines may have specific documentation requirements for minors, especially in cases of custody or parental consent. For example, if one parent is deceased, the living parent or guardian may need to present a copy of the death certificate along with the child's travel documents. Alternatively, if there is a custody agreement in place, a copy of the agreement signed by both parents may be required. These additional documents ensure the child's safe travel and provide necessary consent for international travel.
In summary, while children under 18 may not always need to show ID when travelling, it's crucial to be prepared and informed about the specific requirements of the destination country and the airline. Checking with official sources and staying up to date with any changes in ID requirements will help ensure a smooth travel experience for minors and their guardians. Remember, while a student ID may not be sufficient for airport security checkpoints, a valid government-issued ID or passport is typically required for adults and, in some cases, for minors as well.

A passport is always required for international flights
For domestic flights, the rules regarding student IDs vary. In the US, children under 18 are not required to show ID at TSA checkpoints, only a valid boarding pass. However, some airlines have their own rules about children and IDs, so it is always best to check with the airline before travelling. While student IDs are not accepted as a valid form of ID for adults, they can sometimes be used as proof of identity for minors. This is not always the case, however, and some sources suggest that a government-issued ID is always required for those 18 and older.
For international flights, a passport is always required. This applies to both adults and children. While there are some alternative forms of ID that can be used for domestic flights, such as a driver's license or state-issued ID card, these are not sufficient for international travel. Only a passport or other approved form of ID, such as a Voter Photo Identity Card or a Nationalised Bank Passbook with an attested photograph, will be accepted for international flights.
It is important to note that even if a student ID is accepted as valid proof of identity for a particular flight, it may not be sufficient for other parts of the travel process, such as checking into a hotel. It is always best to carry a valid form of ID, such as a passport, when travelling internationally to avoid any potential issues.
In addition, it is worth noting that TSA requirements are subject to change, and IDs that were previously accepted may no longer be valid. For example, as of May 7, 2025, state-issued driver's licenses and IDs that are not REAL ID-compliant will no longer be accepted as valid forms of identification at airports. Therefore, it is important to check the latest requirements before travelling to ensure that you have the necessary documentation.
In summary, while student IDs may sometimes be accepted as proof of identity for minors on domestic flights, a passport is always required for international flights, regardless of age. It is important to be prepared and carry the necessary documentation to avoid any issues during travel.
