Hello. I'm traveling IAH-MSP tomorrow morning on United. I have a 7:30 pm flight to KEF on Icelandair. My question is this, can I go from terminal 1 to terminal 2 and stay airside? I have PriorityPass membership and due to long layover was hoping to use it at Escape Lounge at terminal 1. Really don't want to do security twice though. Thanks!
