All I can say is I am glad I had a niggling feeling to check tonight. I discovered that as of Monday, someone had been racking up HUGE charges on my account. They over-maxed it. The only reason they were able to do this was because I had been approved for limit increase. My first clue was my balance was about twice what I thought it should be, then I noticed that my available limit was almost NEGATIVE $600!! Because there are still at least 2 days of charges that haven't been cleared and posted yet, there is a difference between what the limit should be based on the balance owing and the actual available limit. The $800 flight was the first thing to jump out at me, then the fact that all the bogus charges were in Pounds Sterling - over $5K in bogus charges! I have no idea where my card could have been compromised, but I sure wish I had checked my balance a couple of days ago. Fortunately, the CC company has been awesome. New card next week and once all the charges have been posted, they will send me a letter with them listed which I am to sign saying that I am not responsible for them and then they all get reversed on my account. In the mean time, what a PITA! I always check my bill carefully and log in a couple of times a month, but I know I will be checking daily now.
