We're hoping to go back to the UK for Christmas this year and were wondering if anyone can recommend any websites or travel agents to contact for the cheapest flights? I know that it's peak season and the most expensive time of year to travel but just wondered if anyone had found good deals with specific companies in the past? Is it best to book online with the airlines direct or are travel agents better? The best we can find at the moment is about $8000 for 2 adults, 1 child and 1 infant - does this sound about right? Would really appreciate any help or advice!
