The necessity of travel insurance has been widely contested by both financial advisers and experienced travelers as it guarantees an immediate room and instant medical attention, yet is only needed seldom. Welcoming travelers' suggestions, Virgin and Qantas Airlines had removed their automatic addition of travel insurance as customers complain of unwanted or unknown expenditures.

According to The Telegraph Travel Contributor Nick Trend -- citing the response of his reader named "Edward" -- travel insurance depends on the traveler. Edward is a traveler with a huge risk appetite who claims he had traveled Europe and the Middle East in the middle of conflicts erupting and never really needed travel insurance. Trend said despite Edward's adventures he may get himself in situations that he needs medical care.

Trend said Edward's point is that travel insurance - as with all insurance policies - only pays out when you only need it else it is a troubled and expensive investment. According to Mozo Australia, furious Virgin and Qantas airline customers echo this sentiment. Complaining of incurred additional expenses they were not mindful as both airlines added the insurance policies without consent, customers lodged complaints against both airlines -- forcing them to remove the auto-addition unless customers ask.

Travelers on a hectic schedule or whose vacation lands on their anniversary or birthday can benefit greatly from travel insurance. If the risk of canceling the flight is quite high or if the traveler is prone to allergies namely from new environments or changing climates, travelers are advised to take travel insurance. Travelers taking a long vacation could also benefit from travel insurance.

For anyone who believes they do not need travel insurance, it would be wise to sign up and use apps that monitor flights for possible cancellations. In the event the return flight is canceled, travelers without insurance must get compensation if it is the airline's fault.
