Hi I’m new to Mumsnet and don’t understand some of the abbreviations so bear with me. We are a family of four two boys aged 12 &13 at time of travel to California next Easter for two weeks. When is the best time to book this trip? Particularly the flights!! Tried Trailfinders and Travel Bag but didn’t come up with what we were expecting. We are looking at starting at San Francisco heading down to LA and finishing off in Vegas. Any recommendations for the trip would be appreciated. Thanks
