I will be flying from Albuquerque, NM (ABQ)> IAD > Rome, Italy ( FCO)
and back again the same route.
On United Airlines.
my concern is about my connection At IAD .
Departing ABQ> IAD> FCO. i have 4hrs 19 minutes connection time in Dulles. On a Tues.
Departing FCO>IAD>ABQ. i have 3hrs connection tim in Dulles. On a Friday.

My first question or concern is about HOW I will GET to my gates (One for international departure, one for domestic) when arriving in Dulles?

Anyone know at which concourses I will arrive for both flights?
AND from which concourses i will depart?

Will I have to collect my bags and recheck? Procedure?

Any info will help this girl who usually flys domestic. TKS!
