I've been wary of relying on credit card insurance for exactly this reason in the past.
I've always taken out a good (but inexpensive) travel insurance policy. Often that has been an annual policy when that has made sense, especially when I've then been able to rely on credit card insurances to back that up.
I've been pleasantly surprised when that has played out well:
- Travel insurance provides minimal cover for delays.
- Credit card (CBA Ultimate) insurance fills the gap nicely.
- AMEX (paid for airfares on Amex) was useless in this case.
On another occasion work trip in US with a side family holiday, hire car on Amex:
- Declined expensive add on insurance on hire car.
- Car was damaged in hotel car park.
- Assumed incorrectly that work travel insurance would cover hire car excess (as I was covered on personal travel added on to work trips under work travel insurance - but didn't read the fine print: doh!)
- AMEX insurance picked up the hire car insurance excess.
