just a little advice from my friends, we booked our flights last feb on my credit card, paid in full and that was that, anyway around september i received a letter saying that the credit card is changing, its a halifax marriott card, the halifax is getting ride of the marriott name, anyway thats that, so the new credit card came today still silver the only differance is not halifax marriott just halifax and the long number has changed, so i rang them to say i have booked my flights with this old card and i have to show them the card when i go to the airport, they said that card is void now, so do i just show it at the airport and i dont have to worry about it or do i panic now, sorry about the full stops (lack of)
