Oh, and also, we're going to Greece this summer on my miles.

If you're connecting to save money and earn the miles then more power to you.
I've always wanted to go to Greece. Colleagues of mine who had Greece on a recent business itinerary loved it, friends that went on vacation loved it. Are you flying BOS-PHL-ATH or BOS-FRA-ATH?
