I have 62,000 BA Executive Club points/Avios (collected through AmEx). I've seen that these are enough for a trip to most places in the world. Should i continue to collect or move? The reason I'm questioning a move is because I'm going to Vegas next month, and I'm flying with Virgin Atlantic. From these flights, I've earned 5,222 Flying Club Points. If i sign up to Virgin's AmEx card, they offer 12,500 points after first purchase. Wise move? Or should i stick to BA? Or maybe do both? I'm worried in doing both I'm damaging my credit rating :s Advice appreciated!
