⏱️ Last-Minute Flights & Strategies

Need to travel soon? Here’s how to maximize your chances of a good fare to ONT within 0–5 days of departure:

• 📲 Monitor low-cost carrier (Spirit, Southwest) apps late at night — unsold seats often drop in price.

🛡️ Travel Insurance Tips

Because Southern California itineraries often include multiple connections, unpredictable traffic or weather, it’s wise to secure travel insurance covering:

• ✅ Trip cancellation or interruption
• ✅ Flight delay and missed-connection protection
• ✅ Lost or delayed baggage — handy if you travel with surf or outdoor gear

🧳 Baggage Fees & What to Expect

• 🧾 Legacy carriers typically charge $30–$35 for the first checked bag (one-way).
• ✈️ Low-cost airlines (Spirit, Frontier) add extra fees for carry-on and checked bags — often $45–$65 per leg.
• 🎒 If possible, travel with only carry-on — especially on low-cost carriers — to avoid large fees.
• 💳 Using travel cards that waive baggage fees can save $60–$140 per roundtrip for travelers with luggage.

💡 Final Smart Tip

When searching for flights to Southern California, always run a multi-airport check including ONT, LAX, BUR, and even SNA. Sometimes a slightly higher fare to ONT offers big savings in ground transport and convenience — other times, a LAX or BUR flight plus rideshare might beat total cost. Compare full trip cost (fare + bags + transport + drive time) before booking.
