For an educational crash course on all things luggage-related, head to this official Tumi retailer, opened by Saeed Zia in 1982. His son Subi, who manages the store, is a luggage whiz who can explain the history behind each brand, list product details as if he’s memorized the specs and even namecheck the celebrities who own the items. For example, he notes that Pippa Middleton carries Knomo’s quilted laptop case ($100) every day, that rapper Flo Rida travels with Tumi’s hard-side rolling packing case ($645) and that David Macklovitch from electrofunk duo Chromeo nabbed Hartmann’s tweed wheeled garment bag ($595). For those of us with real-life budgets, Samsonite’s hard-side floral-print spinner luggage ($199) is an attractive and more wallet-friendly option. Free delivery within Manhattan on all purchases will help make you feel like an A-lister. Mention TONY for 20 percent off all full-priced items through June 21.
