This may well be the intent of the policy, but that's the problem that everyone on here has with this new policy - that intent is not 100% clear and indisputable in the wording of the PDS! I feel no comfort from the fact you talked to a more confident rep, because the vague wording of the policy remains unchanged. And if the policy doesn't explicitly and unambiguously state that it's activated with flights into and out of Australia only, then the uncertainty makes the insurance worthless.
If Amex could learn only one thing from the hundreds of complaints they've no doubt received, it should be that the policy needs amending to clarify basic descriptions of what activates this coverage, such as 'full fare'.
I agree that people will still have issues with the wording, however I thought I'd share what I have heard in order to assist others in making a decision regarding what they want to do.
I would still be nervous if my travel booking was paid for in a piecemeal fashion with different methods etc, however for a straight booking on the Amex I'm now more confident in being covered.
The wording does indicate that the 'trip' is a trip outside your country of residence, starting and ending in that country. So if you pay for this 'trip' that would be my understanding of the coverage activation.
In response to the question about TAC and Public Transport, Taxis etc yes that is correct that you will not be covered if you do not pay for that transport method on your card.
The TAC coverage is a compensatory payment rather than 'travel insurance' so if you were on a train (that you did not pay for on your card) that crashed and you lost a limb you would be covered in terms of medical expenses to patch you up and possibly return you home, however you would not be eligible for the calculated lump sum payout for losing a limb.
As always, everyone needs to make their own decisions about whether they feel this insurance is adequate for their needs and whether they wish to rely on it.
Whilst thehound clearly does not, others might and so I am suggesting that if you've had a poor conversation with ACE in the past, you may have your questions better answered if you speak to them now as they have clearly been taking the complaints and questions on board and formulating a 'house view' about how they would deal with them.
I agree with thehound that whilst they are not specifically detailed clearly in the policy they are open to interpretation and speculation, I feel more confident that they are getting their house in order.
If you were to sue them for a denied claim you could require them to produce the call centre scripts etc that they are using which would articulate this house view, so they would be in a poor position should they choose to tell customers one thing and then assess claims in a contradictory manner... (that's not to say they wouldn't try this, but I doubt anyone on here would give up on a fight easily!)
