There will be a collective sigh of relief on Monday when Airbus officials hand over the first A380 and Singapore Airlines finally gets to be “the first to fly'' it.

The superjumbo may be two years late – with the repercussions of that delay still battering the European manufacturer – but none of its customers is complaining about the quality of the product.

The double-decker aircraft has already passed with flying colours a seemingly unending barrage of tests and is now preparing to face what is potentially its greatest trial: the judgment of the flying public.

Singapore will operate the first commercial flight of the superjumbo between Singapore and Sydney on October 25. It will unveil the last remaining details of its cabin on Monday.

Singapore has opted for a three-class configuration, with 471 seats split into 12 first-class suites on the main deck, 60 business class seats on the upper deck and 399 economy seats on both decks.

SIA chief executive Chew Choon Seng has described the A380 premium products as the most spacious ever introduced by an airline.

Business and economy class passengers who have flown on some of the airline's newly refurbished Boeing 777s will have a good idea what to expect in terms of seating, but the airline's first-class product is tipped to push in-flight luxury to a new level.

The airline is also likely to offer an exceptionally generous 1-2-1 layout of its superwide business-class seats.

The airline has indicated the A380 business seat will be even wider than its 777 counterpart, which was already 50 per cent wider than anything on offer.

Economy passengers will also gain more personal space, thanks to a new seat design that is less intrusive when it reclines.

And everybody will have access to a new entertainment system with more than 1,000 options on bigger, high-resolution screens.

Passengers will also be able to access office software without needing a laptop and download documents to a USB drive.

While there is widespread recognition that the A380 will offer new levels of passenger comfort, the acid test will be whether it meets consumer expectations that have been significantly heightened by airline and Airbus hype.

But certainly the airlines who have invested in the big bird seem pleased with the product.

Pilots who have flown in the giant plane like the way it handles and the extensive testing it has undergone for certification. The planes have in many cases exceeded expectations.

The manufacturer now has 185 orders and commitments – not counting the British Airways' options – from 15 customers.

British Airways recently became the latest carrier to join the ranks of A380 owners when it ordered 12 of the planes, with options for seven more.

SIA and Qantas have both boosted their orders and Emirates, which has 55 on order, has indicated it would like to double that order.

The early adopters believe other carriers will want to order the aircraft once they see it in service, and Airbus is hoping they are right.
