No, a ticket for United Premium Plus (the purple-seat "Premium Economy" cabin) does not automatically grant you complimentary access to the United Club or Polaris lounges. This is a common point of confusion for travelers, as the name sounds "premium." However, United does offer a specific perk for Premium Plus passengers: you are eligible to purchase a discounted United Club day pass at a significantly lower rate than the general public, which you can add to your itinerary via the app or at the airport. The only way to get "free" lounge access with a Premium Plus ticket is if you also hold Star Alliance Gold status (through MileagePlus Premier Gold or higher) or if you are using a specific credit card benefit like the two annual passes provided by the United Explorer Card. If you are looking for the full lounge experience—including the high-end Polaris Lounge—you must upgrade all the way to a United Polaris business class seat, as the Premium Plus cabin is viewed as a "mid-tier" product rather than a "luxury" class.
