Qantas Frequent Flyer - Does QF offer any type of Fast Track for BKK F arrivals?

I am arriving on QF23 in F SYD-BKK at 6:50 PM.

I've heard horror stories recently about BKK immigration lines.

I don't know if that is a busy time and I've always arrived on TG which does offer a Fast Track Service.

If QF doesn't offer anything, I'm wondering if it is worth it to buy the hotel's THB 1000 Fast Track Arrival Service.

Of course if I do buy it, there won't be any line at all!

Can't give an answer on QF Fast Track Cards, but from recent experience, I'd move mountains to get one. Any airline logo on it will do ;). Queues have been dreadful - both getting into the country as well as getting out. There is no effective line control. The few (if any) staff monitoring the situation just try to cram more and more people into the immigration hall waiting area. It makes the worst of the US TSA line ups seem efficient. Don't have a full bladder or be short on time!

I thought that all was needed was a business class boarding pass to use the business class fast track and a 1st class boarding pass to use the red one

Get an APEC card, if you travel frequently enough you should qualify.

They make life so easy, except in Australian airports; where the muppets never seem to control the express lines and it turns into a free-for-all. Try Brisbane for starters...

As far as my experience and the QF staff telling me... QF don't have a dedicated First Host staff who perform such duties as in SYD/MEL/LAX/SIN/LHR...

Can't speak for QF but I'd imagine it's the same. I arrived in F on BA and was given a brown fast track immigration pass. The only thing is that I couldn't actually find the correct desk/area to use it!

On the way back there were special security lanes for J and F passengers and I was given the appropriate fast track pass. This worked extremely well and you actually exit right after the exit to the normal security lanes, so you can see what you've managed to skip ;)

Yes, QF do supply Fast Track cards (when they remember to load them but that's another story).
I've been through twice in the past month and both times got through the normal inbound channel in less than two minutes. Saved my cards for a rainy day.
Such queues as there were, were being actively managed.
I've read of the boarding pass method but haven't tried as yet.
