As struggling airlines add extra-luggage fees and travelers worry about growing security restrictions, services like Luggage Forward and Luggage Free have emerged as ways to avoid the troubles of checking bags. While typically seen as a luxury, more Americans are using such options for run-of-the-mill trips. The idea behind the luggage delivery services is to make traveling as headache-free as possible.
   Customers load up their suitcases as usual, with no special packaging needed. Shipping slips for luggage are mailed to them. A pickup time is scheduled, usually for a two-hour window. If the bags are being sent to a hotel, the hotel worker will typically call customers to let them know their belongings have arrived. Rates vary depending on the weight, distance and speed of the delivery. The new luggage delivery services promise to provide greater convenience by helping customers clear customs, track packages and pick up luggage at home. Still, the price can add up for a big order. But compared to the mess it would’ve caused at the airport, the price was worth it, said Kolodny, a 45-year-old resident of Great Neck, New York.
