I'm sure there are quite a few.
This is a really helpful post. Knowledge and reported experience about which insurers totally exclude coverage for certain conditions and people taking certain medications could help prevent another AFF person applying to the wrong company and being denied cover. I'm not sure if there would be enough data generally available to make a dedicated thread detailing insurers and their exclusions worthwhile though.
Another thought - I personally would not find it worthwhile to take up any insurance that has any condition that is denied cover because an insurer could argue that just about any event was caused by the condition.[
My husband and I travel overseas several times a year and have always relied on our CC travel insurance as we both had no Pre Existing Conditions. This year changed all that, we both have had a few non serious medical conditions that are now deemed Pre Existing. I spent a long time researching the best travel insurance for us ( ages 72 and 66 ), we also wanted an annual one if possible for more than 45 days per trip. The best by far both in terms of fine print and ease of applying was COVERMORE.
Fortunately we haven't had to claim from them and hope we never will but can at least travel with peace of mind that everything is covered. I am of the opinion that if a Travel Insurer can get out of paying, they will.
Interestingly, the quote was cheaper from my travel agency than doing it on line by over $800!!
Hope this helps anyone else in this situation.
