Hello all! I’m planning a trip and will be away for about 4 months (USA/Barbados). My credit card covers 3 months. Does anyone know if I can buy, before I go, an additional month for month 4? My card doesn’t allow extensions, but I though some companies might. Or do I need to buy a full 4 month policy before I go? This happened once before and I did find a policy to buy (once travelling), but it seemed a very costly way to go!
