CANNES, France, Nov 4, 2007 (AFP) - From matching diamond-encrusted mother-and-daughter gold chokers to the latest must-have bags and glasses or a hand-crafted humidor, duty-free goods are increasingly going first-class.

"We are an industry that lives and breathes some of the best brands in the world," Erik Juul-Mortensen, head of the Tax Free World Association (TFWA), told a trade salon here recently. "Let us focus on providing a shopping experience travellers will not find elsewhere."

If the annual TFWA World Exhibition was anything to go by, up-market passengers with deep pockets are heading for a bonanza spending spree while  kicking their heels at airports next year.

And while leading couture houses such as Italy's Versace, France's Hermes and Germany's Boss flew in to the Riviera fair to display their latest designs,  there were also hundreds of smaller specialist  up-market brands, reflecting  burgeoning competition in deluxe accessories for children as well as adults.  

"There  is increasing demand for high-end luxury goods whether it is in  electronics, cosmetics or fashion, and I expect  this trend to continue," Colm  McLoughlin, who heads up Dubai Duty Free, told the TWFA magazine.  

As a result,  business in the fast-growing number of duty free outlets in  airports, cruise-liners, ferries and shops is expected to  keep growing,  industry experts here said, getting an extra boost from the rising number of  travellers worldwide.  

Duty free shops in the Middle East, Dubai in particular, are experiencing  massive growth. But it is in Asia, notably  South Korea, Macao and China, where  the shopping bonanza is really taking off, a TFWA spokeswoman told AFP.  

The buying surge should help the industry reach the 30-billion-dollar mark  this year, said Juul-Mortensen.  Despite security scares, international air passenger traffic rose 8.6  percent in August 2007, the fastest growth rate  for 16 months, according to the International Air Transport Association (IATA).

With airport restrictions on carrying liquids and gels still in force in some countries, there was added interest in the  huge array of fashion accessories on offer at the TFWA show.  

Woman's handbags remained one of the most  popular accessories, but  legendary leather goods companies from Hermes to Dior and Ermenegildo Zegna are  facing increasing competition from less pricey brands such as Furla, Longchamp  and Korean-owned MCM.  French brand Longchamp's new "Legende" line is one of the season's must-haves.

After being photographed on  the arms of British supermodel Kate Moss and pop icon Madonna, the bags have sold out in high street stores but are available duty free.

"All the duty free operators want to stock our bags, it's a great opportunity for us," Longchamp's Sandrine Wezel told AFP.

Deluxe kids' accessories are also catching on around the world. After starting out life in Japan, the "Hello Kitty" brand is fast becoming a cult with youngsters and their mums, and a new luxury range designed by Victoria Couture in France that includes diamond-studded gold kitty necklaces costing from 390 euros up to 2,250 euros (563-3,251 dollars) is taking the  brand to new heights in duty free stores.  

The range, including "mother and  daughter" tops, belts and bags, will  shortly become available in around 40 retail points around the world including  China, in time for next year's Beijing Olympics.

"There's a definite increase in luxury products for children,"  explained  France's Kidow chairman Eric Lemoine.  Until recently, children's accessories and gifts in duty free stores tended to be cheap

"But today's business travelers want to buy more valuable presents  to take home and  this is promoting this new market," Lemoine told AFP.

 His brand includes silver and diamond napkin rings and  high quality  lacquered music boxes that play "It's a wonderful world".

It is the same story for scarves, ties or  sunglasses, perennial favourites  with duty free customers.  

"The luxury end is growing steadily," said Lidia  Flazone of Italian silk specialist Mantero Seta, which makes ties and silk squares for top world  brands.  But  perhaps the most unusual expensive accessory at the duty free  extravaganza was a range of hand-made leather  pocket humidors for connoisseurs  who want to ensure cigars will not dry up even in the most extreme conditions.  

The exclusive leather cigar cases made by French-based Fallon retail at 250  euros for a crocodile leather case up  to 5,835 euros for one made of stingray  skin.  And cigar lovers can also purchase a limited edition Fallon handbag,  matching the humidor and containing a pouch in the bag to hold "sir or madam?s"  pocket humidor.
