I agree, the Thai authorities have been reticent even to permit international to internal transit at BKK for passengers participating in the sandbox scheme. I can see reference on the CAAT website of a scheme for international transit where both flights would need to connect on the same international pier at BKK but that scheme is marked as not currently valid and there is no indication why it was invalidated and what if anything is currently in place.

I would be contacting the local Royal Thai Embassy for advice on if any transit arrangements exist at BKK.

Additionally you need to understand if your ticket is on a single PNR and whether you would be checked through for baggage and boarding pass by JL through to AUH. If there is any dependency on needing a transit desk at BKK to be open, this could again be a considerable risk where the airlines you are proposing to use do not use the connecting airport as their hub.

If you need to get to AUH you would be strongly advised to seek a direct flight or go via a nation that clearly publishes airside transit rules. Whilst AA have sold this ticket, it might only be possible to fly it as ticketed if you are Thai diplomat or other VIP as far as Thailand is concerned. Remember that airlines are never responsible for passengers ensuring they meet the immigration, customs and health requirements for their journey.
