Travellers need to know what is covered.
Malcolm Tarling, spokesman for the ABI, said: "[Customers] should actually understand what they are covered for. The essentials - what you would like to be covered for when you go abroad - are medical expenses and loss of baggage and possessions."
He added that not all travel insurance deals will cover the cancellation of holidays in situations such as the outbreak of swine flu in Mexico.
The ABI stated that not all policies will cover this risk as a travel policy which covered a person for everything would be unaffordable.
All non-essential travel to Mexico has been advised against by the British Foreign and Commonwealth Office.
