In Dublin you go through Irish security and are asked to wait in a pleasant but congested area until the monitors tell you to proceed to US Preclearance where you go through immigration and security. Then you proceed to the 51st and Green lounge. My question is, has anyone gone through the preclearance before being called to do so? I'd rather wait in the post-security lounge if I can get through the US areas sooner.
Thanks for any help.
