At the beginning of this year, Amtrak opened its brand-new Moynihan Train Hall in New York City, complete with an absolutely spectacular Metropolitan Lounge.(Photo by Zach Honig/The Points Guy)I visited shortly after the lounge opened, and I was gasping (under my mask) at every turn — Amtrak’s previous Penn Station lounge was a borderline disaster; I never expected to want to arrive any earlier than absolutely necessary to catch my train.(Photo by Zach Honig/The Points Guy)It’s really exciting that we finally have a fancy Penn Station lounge to visit — even if the current food and beverage offerings leave a bit to be desired. Metropolitan Lounge access is limited to Select Plus or Select Executive elites, passengers traveling in Acela first class and customers with a sleeper-car ticket.I’m almost always passing through with a coach or Acela business class ticket, so I wasn’t expecting to visit again for quite some time — until a special Amtrak invitation hit my inbox this week.Screenshot courtesy of Amtrak.The pass attached to the email is valid for me and one guest. It can be used anytime between now and April 30, and I only need to present the pass to get in — Amtrak’s waiving the usual same-day ticket requirement.It’s unclear exactly which cards will trigger this invitation, but it’s worth checking your inbox if you have the Amtrak Guest Rewards® World Mastercard® or the Amtrak Guest Rewards® Platinum Mastercard® — the latter of which doesn’t carry an annual fee.Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
