A first look at the promotional fares on sale this morning on Scoot, the new low cost wide body brand for Singapore Airlines, shows that it has gone straight for the throat of its parent full service airline.

We will pass over the PR fluff on this and go directly to the fares.

On 26 June, when regular services start between Sydney and Singapore on a daylight flight, Scoot is offering a promotional basic fare (without extras like checked baggage or pre-paid refreshments, or legroom) of $88.

For the ScootBiz (premium) cabin, with only 32 seats, the promotional fare is $388, which includes your legs, meals, drinks, entertainment! and a checked bag.

On the same day, Singapore Airlines is offering one way economy fares of $756.48 or $854.48, or return fares of $946.96 to $1366.96, which are full service fares, with adequate legroom (or an inexpensive preferred seat bulkhead/exit row upgrade).

Singapore Airlines doesn’t offer a premium economy option (other than the legroom upgrade) but its business class on the same day sells for $4185.96 return or $3158.98, which is a sure fire way of discouraging mix n’ match bookings on Singapore Airlines one way and a different carrier on the way back.

One needs to be cautious too about what Singapore Airlines actually offers in business class from Sydney. It’s super deluxe business class is only flown on that route at present on Airbus A380s and when they are used as substitutes, its 777-300ERs. The other jets it uses, the A330-300 and a 777-300, have non-really-truly-flat-horizontal sleepers instead putting you on a wedgie-sloper format in which your legs slide down into a pit under the seat in front while your underwear stays in the same spot and gets dragged up your backside.

While Scoot will no doubt post somewhat higher fares than these promotional offers, it does look like there will be a gap amounting to many hundreds of dollars between them and parent Singapore Airlines which could prove rather more painful for the airline than a wedgie-sloper is for its customers.
