Carlton Leisure are not members of ABTA and those considering using this company or its offshoots might like to see a list of complaints compiled at Carlton Leisure Watch. Companies using the same ATOL registration number as Carlton include: A1 Flight Group. 99 Flight A1 flightcentre Business Class Flight Carlton Leisure Corporate Travel Carlton Travel & Tours Dearflight South America Flight Tickets To America Travel Consultants Travels Or I have had issues with refunds following an airline cancelling flights that I had paid for a month earlier and deductions attempted despite Carlton's terms and conditions. I wouldn't say they were rude, but their service and attempts to charge when they have no right to leaves a lot to be desired.
