When I look up a holiday price stating 7days it includes accommodation and airfare,when I increase my booking to 14days it doubles its price shouldn't it just be another 7 days accommodation increase can anyone explain to me why airfare is included again.
If you book flights and hotel separately you also need to add the cost of transfers from the airport to your hotel. Also, if your flight is delayed / cancelled any consequential changes to your hotel booking are at your risk.
It`s not necessarily cheaper to book flights and hotel independently. The travel agents broker deals with scheduled airlines whereby they get a good discount (according to how much they spend) and should pass on some of that discount to the customer. It`s worth shopping around, in that respect.
