Charismatic actor George Clooney showed moviegoers the "feel good" benefits of being a frequent flyer in the film Up In the Air.
Australian frequent flyers enjoy a similar boost when accrued loyalty points give them access to airline lounges, upgrades or free flights.
Hotel chains have a similar program, and shipping lines also ensure that frequent passengers have access to exclusive onboard lounges and the chance to buy future cruises at a reduced price with points gathered from every day spent at sea.
So what are some of the benefits which are offered to frequent cruise guests?

Frequent cruisers Canada-based Bob Browne and his wife Anne met on the Empress of England in 1968 and have continued cruising, recently notching up more than 40 cruises.As Diamond Plus members of Royal Caribbean's Crown and Anchor Club they enjoy many benefits as frequent cruisers and agree the extra touches make them feel special for being so loyal.
"Through the years we've made many friends onboard, and we always catch up in the ship's Concierge Lounge to discuss our next voyages," says Bob, a retired actor and stuntman.
The crew are "like family" and often call him "Big Bad Bob" as he was a larger than life bad guy in Hollywood movies.
"I wasn't a pretty boy, but I was built like a footballer with a killer voice."
That voice saw Bob appear in 64 commercials from coffee to cars. Anne and Bob always book the suites at the back of the ship.
"We like to see where we have been, and what is coming up along the sides, especially in fjords and canals."
Next February Bob and Anne notch up further cruise points as they circumnavigate New Zealand on Radiance of the Seas. royalcaribbean.com.au/crownandanchor
