If you are offered a voucher and dont take it, a lot of insurance companies wont pay out.

Problems I can see with vouchers (no experience of the BA one though) are some companies require you to phone up to use them, some companies exclude special offers or discounts, some are for rack rate only prices.

The other issue I can see happening is that airlines/hotels etc will be wanting to recoup their losses somewhere, and people with vouchers are the ideal target.

If you take a voucher, be prepared for a price hike. Its like Deal or No Deal. Whats in the box?

Remember, take a voucher and then the airline goes bust, you loose everything. Vary vague as to weather credit cards or insurance would have to cover that.
Credit cards would cover for loss of original booking, but effectively your getting a refund voucher so credit card companies may be getting legal advice on that one.
