Baggage and Transit Information

Familiarize yourself with the baggage allowances of the airline you choose. Most airlines have restrictions on size and weight. For connecting flights, ensure you have enough time between flights to comfortably make your connection, especially if changing terminals. Ontario International Airport is relatively easy to navigate, but allow extra time during peak hours.

Direct vs. Connecting Flights: Which is Right for You?

Direct flights offer the quickest and most convenient travel experience, but they typically come at a higher price. Connecting flights can save you money, but they add travel time and the potential for delays. Consider your priorities – if time is of the essence, a direct flight is the way to go. If you’re on a budget, a connecting flight might be a better option. We clearly display both options, allowing you to compare and choose what suits you best.
