Hello everyone

I'm on the following:

LHR 0755-1110 IAD
IAD 1216-1346 BOS
BOS 1726-1909 ORD

(mad itinerary booked so that I could get more miles and requalify for *G, that extra connection means everything).

Now, the IAD International-Domestic connection time of 66 mins seems very optimistic indeed.

So, my question is -- what happens when I miss that connection? Do they re-route me straight IAD-ORD (something I don't want, as I won't requalify for *G)? How do they re-route me? Can I 'force' them to route me via the BOS intermediate airport?

Thanks everyone!

LHR*G
