Great review Mark.
The facilities after US Pre-clearance are poor. The trick is to wait a bit longer in the lounge and hit Pre-clearance shortly before boarding.
As you said, arriving in the USA as a domestic passenger saves a lot of waiting.
You don’t mention whether you’re a member of the Aer Lingus Gold Circle Club.That one trip would earn a decent number of points which would have a real benefit to you. Drop an email to <a href="mailto:[email protected]“>[email protected]
Hope you enjoy your return trip, Mark
