Seats.aero vs Qantas website

[VPS]

I've been looking at some flights from Adelaide to UK and Qantas is showing availability from a number of cities but when I get to the booking stage I get the dreaded

Qantas website error #4002 [0]​

which AFF says

• What the Qantas website says: “An error has occurred in our central database. Please contact us for further information.”
• Why this error appears: This error message can appear after you’ve already selected all of your flights, but the website is unable to calculate the fare/taxes and crashes before quoting them. The itinerary is probably too complex.
• What to do: Change the itinerary and try again, or call Qantas to book.

It's a simple two flights in the Multi city booking tool so I don't think it can be that complicated.

If I look at seats.aero none of these flights seem to be available so do you think they are actual reward seats

I'm thinking their might be a problem with seats aero. In the last 24 hours a dramatic lessening in awards Australia to SIN or BKK. I can find several SQ flights during January on SQ and UA which normally show up on seatsaero either on aeroplan or UA but none are. I was seeing a bit of TR and now none suddenly.

It could be both then

I think I've tried about 20 combinations on Qantas and keep getting the same error

Are you trying to book PER-DXB-LHR using the QF website multicity tool? If so, it’s probably a married segments issue.

The through flights should appear if you just search for PER-LHR on the Qantas website. If they’re not coming up then there is probably no availability on these as married segments.
