Many non-stop or 1-stop flights can be found from Philadelphia to Los Angeles. The wedding venue is about an hour away (without heavy traffic) from LAX. The major freeway to get to Orange County is called the 405.

Another option is to fly into John Wayne Airport, Santa Ana. The wedding is actually much closer (about 20 minutes) to this airport, however, many flight options will have at least 1-stop. We have flown in/out of John Wayne and don't mind the layover. We would recommend this option if you aren’t renting a car.
