Might be a good time to start following the IAH (Bush Airport) Twitter (X) account or on Instagram
This seems to be effecting more of the departures since a lot of TSA workers are not showing up for work due to the Government Shutdown. Going to be a crazy week.
I just went through IAH yesterday. Standard security lines were at 3+ hours. TSA Pre got me through in 20 minutes. Clear was about the same, so use them if you have them!
