Short answer — many upscale NYC hotels routinely offer complimentary upgrades and additional perks if you book through certain channels. The easiest ways to get them are booking through (1) American Express Fine Hotels & Resorts (FHR) if you have an eligible Amex Platinum/Centurion card, (2) a Virtuoso travel advisor (or other luxury-travel advisor networks), (3) Hyatt Privé / brand-specific “preferred partner” travel-advisor programs, or (4) directly via a hotel’s luxury/partner booking channel (Four Seasons Preferred Partner, Park Hyatt/brand programs, etc.). Each channel typically includes early check‑in (if available), room upgrades (subject to availability), daily breakfast for two, a hotel credit, and late checkout — but exact perks vary by program and property.

Quick practical tips to increase your chances of an upgrade or perks

• Book through the program that the hotel participates in (Amex FHR if you’re eligible, a Virtuoso or Hyatt Privé advisor, or the hotel’s preferred‑partner channel). Always confirm the “rate / package name” (FHR, Virtuoso, Privé, Preferred Partner) when booking so the hotel will apply the amenity set. (americanexpress.com)
• Put your loyalty number on the reservation if you have status (you typically still earn loyalty points and status credit, and status can help for upgrades). (House rules vary by brand — ask the advisor or hotel to confirm.) (qxtravel.io)
• Ask the booking agent or travel advisor to note the booking as a Virtuoso/FHR/Privé reservation and to attach the amenity code/reference. That
