San Diego International Airport (SAN)
The San Diego Airport is convenient if you are going to Downtown San Diego, but it is a bit of a trip for Kaaboo. Kaaboo takes place in Del Mar, which is about 15 miles north of the airport. Technically there is a train that will take you to Solana Beach, which is close to Del Mar, but it is not worth the trouble and inconvenience. Your best bet is to take an Uber, which will run you about $25 each way. You can also look into renting a car from the airport. If you do go with an Uber you can snag one from either terminal of the airport, just outside the baggage claim area.
The cost of a rental car or an Uber will run $25-30 typically to Del Mar.
Generally the cheapest time to book flights for Kaaboo Del Mar will be about six weeks before Kaaboo Del Mar. This means you should be focused on booking your flight in Aug. 3, 2018. This may seem late to you planners out there, but statistically it's the cheapest time to book flights. That said, if this is too late for you book it earlier. One final note is that plane tickets for Kaaboo Del Mar tend to skyrocket about two weeks out, so certainly don't wait that long to book a Kaaboo Del Mar flight.
