I searched this forum for similar threads but didnt find the exact answer to my question - hope someone can help.

I am flying MXP-BRU (on SN) connecting to BRU-IAD-RDU-IAH (all on UA). I am enrolled in Global Entry but the wife isnt. I know at IAH there is a short line for passengers with only hand baggage, which allows them to clear CBP almost just as quick as GE. Is there something similar at IAD?

As for baggage, I am assuming SN will check my bags all the way to IAH. Do I have to collect my bags and recheck them in IAD for the domestic leg?

Thanks in advance
