Crystal Cruises’ entire 2015 through early 2016 collection of worldwide cruises is now open for booking.

Also, new “Book Now” fares for the remainder of sailings in 2013 and all of 2014, as well as 2015 through May 2016, debuted this week, guaranteed only until October 31.

While current promotions offer compelling savings (up to $7,500 per person!), Crystal did increase fares on 31 voyages.

Complete cruise fares and itineraries are now detailed on Crystal’s website and in new Fare & Itinerary Guides that showcase Crystal’s new stateroom categories, including the recently-announced allergy-friendly Deluxe PURE Staterooms, as well as Penthouse amenities, Crystal Serenity and Crystal Symphony deck plans, and special offers such as 2-for-1 Air Add-Ons in Australia and Asia, Low Solo Fares, Kids Sail Free, and the Crystal Family Memories Program.

“Publishing itineraries and fares as early as we have has been a terrific tool for agents.  They have more product to sell, and it helps lock in family reunions and personal milestone celebrations,” says Jack Anderson, Crystal’s senior vice president, marketing & sales.

“Additionally, agents encourage their clients to book their future cruise on board, which offers a savings to the client and promises repeat business and booking credit for the agent.  Agents selling Crystal also know that rates are only guaranteed for the two-month Book Now booking window.  They really knew 31 cruises went up in price on August 31 and that there will be cruises that go up in price again on November 1.”
