Thanks for the info guys. Yeah, I'm taking UA non stop to phx from IAD. Actually, the iad-phx leg is on a separate PNR. I have to be in DC for work Monday and Tuesday the 19th and 20th, so I have work obviously paying for my phx-iad ticket (dept 11/18, return 11/25) and I am seeing my family in the UK in between those dates. I'm hoping I can check in as well for my iad-phx flight when checking in for my lhr-iad flight on 11/25.
