Wow, I really appreciate everyone's thoughts on this. We will re-think our plans. For those who mentioned the "flat tire rule," I don't know what that is. Would you explain further? The transatlantic flight is on United, but they are award tickets and so at this point we are waiting to see if award seats from DEN-IAD open up . . .
I suppose we could also figure out how to just go with carry-ons . . .
