Flight
During the summer, three airlines fly between Manchester and Los Angeles. Thomas Cook is usually the most affordable and have direct flights. This is probably the best option. Aer Lingus is a little more expensive and you stop in Dublin. However, you can go through U.S. customs there and therefore get through LAX faster. Virgin Atlantic also run direct flights from Manchester but prices are high.
Travel Note
There is a shuttle bus that runs from LAX airport to Santa Barbara.
