CAA (Civil Aviation Authority) and ATOL (Air Travel Organiser's Licence)
American Sky is fully ATOL bonded with the CAA (ATOL Number 9759).
The CAA is the UK's aviation regulator responsible for that include air safety and consumer protection among other duties. It manages the Air Travel Organisers' Licensing (ATOL) scheme. All operators in the UK are required by law to hold an ATOL licence which demands the deposit of a substantial financial bond with the CAA. ATOL protects you from being stranded or losing money by arranging for people abroad to finish their holiday and fly home or fully refunding your payment in the event of any problem with the operator.
