Which factor is NOT relevant for determining the premium of a single trip travel insurance?

The method of transportation is not generally considered a key factor when determining the premium for single trip travel insurance. Premiums are primarily influenced by the length of the trip, the destination, and the age and health condition of the applicant.

The length of the trip is crucial as longer trips often incur higher risks and may result in more potential claims. Similarly, the destination affects premium rates due to varying levels of healthcare availability, risk of natural disasters, or travel advisories that may be pertinent to specific regions.

Moreover, the applicant's age and health condition are significant factors because older individuals or those with pre-existing medical conditions may pose a higher risk for the insurer. Insurers evaluate the likelihood of health-related incidents during travel, which can lead to claims, thus impacting the premium amount.

In contrast, while the method of transportation might be relevant in specific insurance contexts or unique coverage options, it does not have a significant bearing on the overall premium for standard single trip travel insurance policies.
