However if it's simple straightforward cover that you are looking for here are some things that you should look for and expect the insurance to cover you for.

Many sites online, such as Go Travel, offer very reasonably price 'single trip' travel insurance. This type of insurance is sometimes arranged for a set period, such as 31 days, or a month. You can also buy annual cover from this provider, but some insurers offer more flexibility. For instance AA allow customers to purchase up to 185 days worth of travel insurance cover.

Cover can be purchased simply and easily online by filling out a short form. What's more the process is quite rapid and insurance can be arranged immediately - even on your way to the airport. This means that if it is something that you have forgotten about, and left until the last minute, you will still be able to get cover in a hurry. This is good news seeing as travel insurance is a vital aspect of any holiday.

Most single trip travel insurance will provide some type of emergency medical insurance. This means that if you have an accident you will be able to call an emergency helpline and receive top class assistance any day of the week, all year round. Depending on what your insurance covers this could be a worldwide service or limited to a certain area such as Europe. You can also expect the company to provide multi-lingual customer service representatives so that they can help no matter how well the local emergency services understand English.

Single trip insurance will aim to cover your medical expenses. This means that if you find yourself in the unfortunate situation of having an accident and ending up in hospital, then the majority of medical bills will be paid for. The amount will depend on the type of cover that you have opted for and the premium that you are paying. In most cases, the higher the premium, the greater the expenses that will be covered. In order to compare the amount of expenses that are covered by different insurers you can always visit a comparison site such as www.moneysupermarket.com.

On top of the medical expense there is also usually some kind of personal accident cover. This means that if you have an accident that causes permanent damage then you could be entitled to a one off payment. The amount of this payout will depend on two things: first, the level of cover that you have arranged and, second, the severity and type of injury that you have sustained.

Finally, there will be extras dependant on the insurer. Some companies offer payouts should your flight or holiday be cancelled at the last minute. Others will cover you if you are on a business trip, some won't. As with all types of insurance it is very important to examine the small print in the Terms and Conditions and make sure what, and under which circumstance, you are covered.
