Best website to get a VS reward/ miles seat alert?

Hi, having found out for myself that Expert Flyer no longer has VS seat alerts, I wonder what people are using to get an alert for miles seat availability?
Reward Seat Finder seems a bit of a waste of time, as its 99% BA centered? Is there any other option out there, besides manually checking every day?

Looking for Xmas availability, JFK>LHR, (3 Ec seats) and there's nothing at all out there, even for a Au-for-lifer. I would spring for UC if really had to, but... nada.
I can wait if needed, silly me not booking in Springtime, when I saw open seats.

(BA has quite a bit open, its just VS who are being stingy!)

Seatspy.

There’s avail up until the 18th and then again from the 24th.

Thanks for that. I've subscribed for a trial 14days, so lets see. If I need to pay for the year, then so be it.

Yes I see availability (for 3) prior to 20th, but can't leave till 20th night at earliest. Dec 21/22/23rd anytime all good.

Fingers crossed!

Seatspy is great, but with one word of caution!

Recently I didn't receive any notification that my subscription was ending or invitation to renew, so I thought that my alert was still in place only to realise after some time that it wasn't. Luckily I managed to get the seat that I was looking for, but it is worth making a note of your subscription dates just in case!

Thank all, I'm based in the US, and SeatSpy is hardly known here, being UK carrier focused
Appreciate the tip!

Another rec for Seatspy, I use it often to get visibility on VS award seats.

Seatspy has generally been great, but there have been 3 occasions when their data has been incorrect, I did log it with them and they are investigating.

Twice it said there was availability and there wasn't, & once it said no availability and there was over a dozen seats available and I almost missed the seats. Luckily I manually checked and got them.

Part of their USP they say is instant alerts which didn't work !
