Belgium
Brussels Airport isn't a bad place, although the passport queue was a bit slow, and the Diamond Lounge was disappointing. The flight back to New York on a big 787-10 Dreamliner was more than pleasant enough, United even found an edible menu.
The stop at the United Polaris Lounge in Newark (EWR) was a bit abbreviated, but was nice to get a quick bite, and the EWR location is perhaps one of United's best business class lounges. The flight back to Los Angeles was a grind in economy, with strong headwinds not helping, but given I had time on the back end, decided to stop at the Polaris Lounge at LAX before going home. Given lounge access was included with my ticket, why not take advantage of the (surprisingly decent) tuna poke bowl and the (sadly diminished) Polaris burger at the Polaris Dining room??
