Earlier this week, Qantas raised the bar on its now-regular scenic flight adventures and began promoting a two-and-a-half-hour flight out of Sydney to view a supermoon event in late May. If it sounds like fun and you are keen to go, the bad news is Qantas sold out the flight in two and a half minutes. Qantas has also closed the waitlist.

The latest in a long line of successful scenic flights for Qantas

Departing early evening on May 26, Qantas plans to send one out of its Boeing 787-9 Dreamliners out of Sydney and east across the Pacific. The Dreamliner will climb to 40,000 feet to capitalize on dark and clear night skies. Qantas notes in addition to watching the rising of the supermoon, that evening also happens to be a total lunar eclipse. The airline says that is a highly unusual double act.

Passengers will be suitably lubricated by a pre-flight cocktail party and cosmic cocktails. They may even learn something. A professional astronomer will be along for the ride and providing some inflight insights.

This sortie to check out the southern hemisphere night sky follows a series of highly successful scenic flights for Qantas in the past year. That included a seven-hour marathon overflying much of Australia and a weekend to Uluru. More recently, there was a seafood lunch on an island in the Whitsundays. All of the flights quickly sold out.

Blocked seats and presales to premium passengers limit the number of seats available for general sale

The Qantas 787-9 normally accommodates 236 passengers across three cabin classes. But fewer seats were available on the supermoon flight. Qantas blocked off the middle seat blocks in the economy and business class cabins. The 'E' seats in the premium economy cabin were also blocked from sale.

The number of seats available to the general public reduced further after Qantas offered its most elite frequent flyers early access. The airline's best customers weren't shy about taking up the offer.

According to keen Qantas watchers on the Australian Frequent Flyer forum, around 55 seats were left for public sale at midday Sydney time on Wednesday. Qantas confirmed to Simple Flying those remaining seats sold out by 12:03 Sydney time.

"I jumped on at the strike of 12, and there was barely anything left. There was just one window seat in Y left, second last row. But by the time I had got to checkout, my seats were bumped," posted one member on the forum.

"My experience too," posted another member.

Some handy revenue as Qantas capitalizes on demand for scenic flights

Qantas began waitlisting hopeful would-be passengers, but the demand was so high, that waitlist has now closed as well. The airline was selling economy class tickets from US$385, premium economy class tickets from US$694, and business class tickets from US$1158. Note the word "from." Qantas was charging a premium for a window seat - and that's fair enough.

But with 24 seats initially available for sale in both the business class and premium economy cabins, and 112 seats initially up for grabs in the economy class cabin, Qantas pocketed over US$87,500 from ticket sales.

To date, Qantas has been operating many of these flights largely on a cost-recovery basis. The airline is keen to keep planes and crews in the air and the Qantas brand firmly in the spotlight. But as the popularity of the supermoon and previous scenic flights attests, there is a lot of demand out there for this kind of flight. It's an interesting, albeit niche, way for the airline industry to do business in the future.
