Safe traveling means not just traveling when one feels grand for a person with pre existing medical condition. When one becomes clear by the doctor for travel and having all your medicines during the flight. One must declare one's specific medical condition or purchase what they call travel insurance with medical conditions to be fully covered during travel.
Standard Travel Insurance
It is different from travel insurance with preexisting condition. It's covered any cost that is associated with the medical condition. One suffers from a heart attack, regular travel insurance will not pay for the cost of the medical expenses. It's covers expenses that are caused by your travel, such as if he plane crashes. For someone traveling abroad, the cost of treatment, hospital, medicine and having to stay longer abroad can cause a big dent in one's finances. This insurance does not cover medical conditions and encourage travelers to purchase this insurance with medical conditions.
