I have an Indian Passport, and I am traveling FRA-IAD-BUF (Frankfurt-Washington(Dulles)-Buffalo. I have a single Lufthansa ticket, however the connecting flight from Washington to Buffalo is United Airlines.
Given that Washington is the port of entry, will 1 hour 30 mins be sufficient to catch the onward flight?
Do I need to re-checkin the baggage(for customs)? Or will it be forwarded to Buffalo?
What happens if I miss it? Will Lufthansa schedule me on the next flight?
Also, given the baggage allowance of 23*2 for international, if a new flight is booked from Washington to Buffalo, will I be able to carry it?
