Megamiles: Fortunately, there are two different flights, depending on whether I want to fly out of ORD or IAD.
Merry Flyer: I should have been more specific about _Frankfurt_ leg I was referring to. I meant the stateside-Frankfurt legs -- the ones that really count! That last hour and half jaunt to Prague really isn't a huge concern for me, unless of course I have to fly British Midland again. Ugh.
Thanks all for your replies.
