Any affordable COVID travel insurance to recommend? Below 1000 THB for 7-15 days

I am arriving in Phuket from the uk on a Emirates flight 12/12/21 my question is in regards to travel insurance requirements.

It’s states in my flight details I have travel insurance included with my Emirates booking. Has anyone had this accepted at check in?or would I be best to buy separate insurance?

When I was in Phuket this August I used the AXA “ covid cover “ insurance that stated on the certificate I was insured in the event of contracting Covid-19 …..

Just thinking if my insurance with my Emirates flight will cover me then is a waste of money paying for a second policy.

Any help would be great 🙂
