Only a few days ago we reported that Singapore Airlines had shifted to all-flat-bed Business Class operation on flights to and from Australia and New Zealand. Well hot on the heels of that welcome development, another relatively distant route is soon set to enjoy the same promotion to flat-bed status.
From 1st January 2020 the airline will be swapping out an older Airbus A330 with a new Airbus A350 Regional on its third daily Osaka flight.
That gives rise to some rare short-term Star Alliance partner redemption opportunities into the new 2018 Regional Business Class cabin on a long-haul route.
The schedule
We first reported on Osaka getting a third daily Singapore Airlines flight back in February this year, with the extra service starting in late April.
The bad news was that an Airbus A330 was to fly the additional flight, meaning angled beds and many seats without direct aisle access in the Business Class cabin.

Here’s how the current schedule looks, with all flights operating daily on this route.
Current schedule (until 31st December 2019)
Flight | From / To | Aircraft | Seats |
SQ618 | SIN0130 – KIX0845 | 787 | 2018 RJ |
SQ620 | SIN0825 – KIX1540 | 333 | 2009 RJ |
SQ622** | SIN1405 – KIX2120 | 787** | 2018 RJ |
SQ619 | KIX1100 – SIN1700 | 787 | 2018 RJ |
SQ621 | KIX1655 – SIN2305 | 333 | 2009 RJ |
SQ623** | KIX2330 – SIN0530* | 787** | 2018 RJ |
* Next day
** SQ622/623 is operated by an Airbus A380 Version 2 from 27 Dec 2019 to 6 Jan 2020 – see our article for details.
With the exception of short-term A380 operation on SQ622/623 for 11 days over the Christmas / New Year period, the Osaka route then shifts to all 2018 Regional Business Class operation.
New schedule (from 1st January 2020)
Flight | From / To | Aircraft | Seats |
SQ618 | SIN0130 – KIX0845 | 787 | 2018 RJ |
SQ620 | SIN0825 – KIX1540 | 359 R | 2018 RJ |
SQ622** | SIN1405 – KIX2120 | 787** | 2018 RJ |
SQ619 | KIX1100 – SIN1700 | 787 | 2018 RJ |
SQ621 | KIX1655 – SIN2305 | 359 R | 2018 RJ |
SQ623** | KIX2330 – SIN0530* | 787** | 2018 RJ |
* Next day
** SQ622/623 is operated by an Airbus A380 Version 2 from 27 Dec 2019 to 6 Jan 2020 – see our article for details.

This schedule change suggests that the 11th Airbus A350 Regional due to arrive in the Singapore Airlines fleet, 9V-SHK, should deliver in December 2019 shortly after the last long-haul A350 variant (9V-SJA).
Older 2009 seats on Japan flights until March 2020
As many of our readers will know, Singapore Airlines runs a seasonal service to and from Sapporo each winter. This year it’s operating from 30th November 2019 to 6th January 2020 (Singapore departure), using an Airbus A330.
The last Sapporo – Singapore flight departs on the morning of 7th January 2020, which then leaves only one Japan flight each day with the older products.
That’s SQ630/SQ639 to and from Tokyo Haneda, which is operated by a Boeing 777-300 (non-ER) with the 2009 Regional Business Class seats.

The good news is that from 27th March 2020 that flight is scheduled to change to a Boeing 777-300ER with long-haul 2013 Business Class seats, which will finally see all of SIA’s Japan services operated by aircraft with flat-bed Business Class seats from the start of the summer 2020 schedule.
SilkAir continues to operate to and from Hiroshima using Boeing 737-800s with recliner Business Class seats.
KrisFlyer redemption
These are the KrisFlyer redemption rates you’ll pay flying SIA between Singapore and Osaka, which are also valid for all Singapore Airlines flights between Singapore and Japan.
KrisFlyer Redemption Singapore ⇄ Osaka |

Saver | Advantage | |
Economy | 25,000 | 45,000 |
Premium Economy | 34,500 | n/a |
Business | 47,000 | 70,000 |
First / Suites | 70,000 | 120,000 |
If you already hold a confirmed ticket in Economy Class, these are the rates to upgrade to Business Class on the Osaka route.

Economy Standard (Class: M, H, W) |

Economy Flexi (Class: Y, B, E) |

Quite close to the full saver redemption rate as usual, so this is probably only of interest if your company has paid for your Economy ticket from the outset.
Other FFPs
Once Singapore Airlines changes aircraft type from one with the 2009 Regional Business Class to their newer Business Class sats, they eventually restrict that cabin for redemption by KrisFlyer members only, plus Alaska Mileage Plan and Lufthansa Miles & More members. The good thing is that, for whatever reason, it takes them some time to do this.
As usual we are seeing good award availability for Star Alliance partners in Business Class on the SQ620/621 flights, even though the new product is flying from 1st January 2020.

It will cost the following number of miles or points to redeem to Osaka from Singapore (or vice-versa) using miles from another Star Alliance or partner programme:

Aegean miles are offering by far the best rate on this route at 21,000 each way, though they are hard to come by for most of our readers unless you secured them in one of their occasional promotional sales. It’s also a steal in Economy Class with Aegean – at 12,500 miles that’s half the rate charged under KrisFlyer.
For the more widely held currencies, Turkish Miles&Smiles is a good option at 30,000 in Business Class, as is Lifemiles at 36,000 miles.

If you are interested in locking in a redemption with miles from a Star Alliance or partner programme, we’d recommend doing this sooner rather than later as eventually these newer seats are likely to be blocked to all except KrisFlyer, Lufthansa Miles & More and Alaska Mileage Plan members.
Reviews
We have two comprehensive reviews from our firsthand experience of the 2018 Regional Business Class; one of the window seats and a shorter but still detailed look at the ‘couple’ middle pairs, which are available at alternate rows on aircraft with this product installed.

Those will help you learn what to expect from these new products if you haven’t flown them before.
Summary
It’s good to see yet another relatively distant city pair served exclusively by flat-bed Singapore Airlines seats in Business Class.
In fact from the end of March 2020, all Business Class seats offered by the airline to and from Japan will be flat-bed versions, with the final replacement of the last angled bed products on the Tokyo Haneda route at the start of the summer 2020 season.
Don’t forget that from 1st January 2020 another Japan route gets an exciting equipment swap – with the SQ637/638 Tokyo Narita service receiving the new Airbus A380 Version 3 with the latest 2017 Suites and Business Class products.

If you’re looking to jump on a rare 2018 Regional Business Class award seat to or from Osaka using miles from a Star Alliance or partner programme, there is the usual (and likely short-term) opportunity to do this from January 2020.
You’ll have to act soon in that case, as most partner availability in Business Class will be removed on SQ620/621 in due course.

Hi Andrew, would you know roughly how long it takes for SIA to yank out such partner availability?
There’s no set time in my experience. Anything from a couple of weeks to a couple of months.
