Thanks for the quick reply. Originally, I was going to cut 2 separate tickets, but I see that to expedite things I should have the entire travel itinerary on one ticket.
I think the BA flight out of Athens is the first one to Heathrow. Olympic's first flight, I believe, arrives a bit later..... I'm trying to avoid US east coast airports because of delays and the need to make a late day connection.
Thanks for your input.
