Travel Products - Best Comprehensive Travel Insurance for a RTW Trip?

My apologies in advance if this question has been answered elsewhere, I searched and couldn't seem to find anything pertinent to my situation.

I will be travelling around the world for close to a year using AA frequent flyer miles. I'll be going to every continent and in addition to my main award ticket I will also be purchasing side trips by air, rail, bus, and sea. I'm also going to be doing some extreme sports (skydiving on every continent, hopefully!). I'm looking for a travel insurance policy with comprehensive coverage (emergency medical, evacuation, delay, cancellation, death in the family, adventure sports, loss, etc.) but I'm not sure which companies are the best and most reputable. Friends have recommended Allianz (which AA referred me to) and Zurich, but I was wondering if anyone here who has done something similar has another suggestion. Thanks in advance for any assistance you can render!

i couldnt find one, nor could i find discussion

i bought 10 days of relatively comprehensive Allianz on united.com for $25 a head. we are going to bcn. i am 74 with a heart problem. i did not read all the fine print, but there was enough in there to make it well worth the price. they would haul me back to usa. if i were doing your trip, i would consider one of each, and compare to see if one was more inclusive. the allianz had most of the buzz words in it, and i saw no "pre-existing" condition clauses.

Insurance offerings seem to be based on whatever is your home market. Also many policies marketed through completely different channels and under different brand names seem to essentially be the same policy underneath underwritten by the same underwriter e.g AXA, Mondial, the former AIG).

Things that matter to me include is there a helpline that I or a medical person attending me can call worldwide, which will actually take care of organising whatever needs to be organised, as compared to a policy under which I must do and pay everything myself, and then claim on return? Also if travelling on business, many policies exclude this or do not offer sufficient coverage for business equipment.

For what it's worth, I purchase quality worldwide annual coverage each year and this year I went for a policy from Amex purchased in the UK. I;m willing to take a high excess, but I don't skimp on cover. Check carefully any excluded countries or types of activity. US-underwritten policies typically ban about 4 standard countries including Cuba.

If you're in the UK market, there is an institution called defaqto (google it it's spelled d-e-f-a-q-t-o - yes that really is a lowercase letter Q in there) which seems to provide independent evaluations of all types of insurance policies. I'd start there in my research if you are new to this. My experience matches their notes on the policies I have had. Consumer organisations e.g. in the UK, "Which?" also often publish regular evaluations of insurance products amongst other products they evaluate. For cross-comparison a comparison site, e.g. moneysupermarket.com, in the UK may offer some fascinating quick ideas.

Personally, I wouldn't leave without medjetassist or similar as a secondary.

I bought a year-long policy from Delta.com mainly for emergency e actuation coverage. As I am noe on Medicare I found a supplemental that covers emergency treatment. Hope I never need to use it, but it is reassuring to have.
