Thank you everyone for your help.
The last time I flew I was with AllClear it cost £1297.65 and as you can imagine I am looking for something less expensive. Admittedly it was a multi trip travel insurance with full cover for Covid.
However, since then I have had a heart attack and to cap it all I had a biopsy yesterday on what was thought to have been a keratosis and will be having the results via FaceTime, during my holiday. I will obviously need to fill them in on that.
So I will get on the case now and update you on the result.
Once again many thanks to you all.
