The answer to this is NO.
ABTA or the Association of British Travel Agents is an industry body aimed at travel agencies. At Menorca Walking Holidays we provide the service ourselves and don't sell other peoples holidays. ABTA, therefore, is not relevant to us.
ATOL or Air Travel Organisers Licensing are a Civil Aviation Authority body set up to cover the eventuality of your flight provider going bankrupt. The flight is not included within the Menorca Walking Holidays price and, therefore, ATOL is not a requirement for us. We do, however, strongly recommend that whoever you book your flight with is ATOL bonded.
