I am not a frequent flyer but I have accumulated about 450,000 in 3 credit cards and I am trying to figure out how I can combine to pay for airfare. I am traveling with my family at the end of July to Amsterdam, staying for about 10 days, then flying to Greece for two weeks. I can depart and return at either NY/NJ area or PHL. I am trying to fund as much of the airfare for the four us by using the points. I have about 210,000 in AMEX Gold, 100,000 in AMEX Blue and 145,000 points in a Bank of America VISA card.

What is the best way to use as many of the points as possible? Should I go with one airline? Can I use services like Travelocity or Expedia? Can I use more than one airline?

Any help would be much appreciated.
