EU Citizen Traveling with Non-EU Citizen Spouse - EES Impact

My wife and I are traveling tomorrow to Lisbon from a non-EU country on a non-stop flight. We’re returning a week later. I’ve been reading about long lines through immigration on both arrival and departure. This apparently is especially true for lines dedicated to non-EU citizens. My question is, can my wife join me in the EU citizen immigration line? She is US citizen. I’ve seen a post or two that say yes, but would like to confirm, especially if someone has a recent first hand experience.
