I have managed to book an alternate flight at an extra cost of £1,000 because they couldn't provide a suitable alternative.In their T+C they state that they will provide a similar or better alternative,which in this case they did not,can I claim back the difference? Also interesting is that the airport has no record of this flight ever being on their system, take the booking,then the money,cancel the flight and offer something else,[problem] or honest mistake?Comments please

airtours has cancelled my flight on may 16th,which has been booked for 12 months,they have offered an alternative a day and a half later which is not convenient,can I claim a full refund and any compensation? I need the money back to try and book an alternative myself.We booked a villa in Florida seperately and would have nowhere to stay for the last day and a half
