What are the requirements for traveling from Thailand to Singapore and back in a day?

You probably need more then one day to achieve this. You will not be allowed to have a meeting before PCR test come back and then need to do ART next day and PCR for your flight back. Maybe not impossible but can't imagine juggling all.

Make sure you on a VTL flight from Bangkok.

Thailand Pass is not going fast for me hoping it is due to PH. I am looking to do the trip to Thailand soon.

Singapore Airlines try to outline requirements both ways in a fairly easy manner. Government page keep changing.

Oh one other thing apart from insurance being a lot less than Thailand you dont need to purchase until after approval for entry

Is this a border run you are trying to do by air?
