Since 1993, all tour operators offering package holidays have been subject to the " package travel regulations".
Some of the components being
To provide financial protection for prepayments and require Tour Operators to provide what is promised, with a guaranteed refund if the operator goes bust, and getting you home if this happens when you are on holiday.
Anyone buying a package holiday in the UK (and I think the EU) is financially protected by the law so all this rubbish about paying on credit card for protection is exactly that, rubbish !!! when dealing with Tour Operators and Travel Agents who are part of ABTA and FTO ( The Federation of Tour Operators)
When something goes wrong, you sue the TO, not the agent who is a sub-contractor of the TO.
Each year the Tour Operators pay a small percentage of their annual turnover into a "pot" that is held for the sole purpose of bailing the consumer out if any tour operator goes under.
ABTA - The Association of British Travel Agents represents both travel agents and Tour Operators .and if you choose to book a holiday where the TO or agent is not a member of ABTA, well that's your problem if they go bust.

Regarding having a months free debt, that is also not true, if the transaction is processed at a particular time of the month, and can be as little as 2 weeks to pay the amount off in full before incurring interest charges, and some credit card suppliers charge you an annual fee for having the card in the first place, also the TO`s insist on having my money 8 weeks before the date of my holiday, making interest in their bank account and making none in mine.

Whilst the final price might be displayed before the commitment is made, I think most peoples gripe is that the price advertised is not the price charged at the end of the booking process"¦ that is deception, misrepresentation and unfair trading.
A stupid way to look at this would be...If I buy a coat, I don`t have to pay extra for the buttons or pockets in it, they are expected to be part of the package of a coat that serves the purpose which it was purchased for, package holidays are just that, everything included that you basically need to get you from A to B and should not be "extras".
