I don't have that flight unfortunately (would of been too good to be true)
here's in my itinerary
United Airlines Flight UA976 on a Boeing 757 (jet) in coach class
Departs Chicago, IL (ORD) Tue, Dec 16 6:11p 1 hr 50 min
Arrives Washington, DC (IAD) 9:01p
United Airlines Flight UA924 on a Boeing 777 (jet) in coach class
Departs Washington, DC (IAD) Tue, Dec 16 10:04p 7 hrs 11 min
Arrives London, United Kingdom (LHR) Wed, Dec 17 10:15a
I really hope my connecting gates are close. I see there is some shuttle service to inter-terminal travel which scares me!!
