North India is under an intense spell of fog this season. Delhi was under a thick blanket of fog on Wednesday which threw the normal life out of gear. Due to almost zero visibility, travellers and daily commuters faced harrowing time travelling from one place to another. Airports in North India saw long queues of passengers waiting to get updates about their flights. At Delhi airport, over 110 flights were affected due to the dense. The operation of Indian Railways trains was severely hit as well as many trains got delayed due to fog-affected visibility. In such situations where travel gets delayed or cancelled due to weather conditions, travel insurance comes in handy. Apart from hospitalisation and loss of luggage, most travel insurance covers loss you incur due to delay or cancellation of flights due to various reasons including weather-related issues. An emergency arising out of the delay is also covered under its ambit. Though everyone should get their travel insured it is highly recommended for frequent fliers who can opt for a multi-trip travel insurance which will cover all their upcoming trips within a specific period for example an annual multi-trip travel insurance will cover all your travels within that year. Frequent or not, travel insurance is always handy.
