Travel Tips
To ensure a smooth trip, consider booking your flight at least three to four weeks in advance to secure the most competitive fares, as last-minute prices for this transcontinental route tend to spike significantly during peak business weeks. Since there is a three-hour time difference between the East and West coasts, try to schedule a morning departure from Raleigh-Durham so you can arrive in San Diego by early afternoon, giving you plenty of time to enjoy a sunset dinner at the harbor. Additionally, keep an eye out for seasonal non-stop options, but be prepared for a short layover in hubs like Dallas, Charlotte, or Phoenix, which can often provide more flexibility in scheduling and potentially lower overall ticket costs for budget-conscious explorers.
