Strengthening the West Coast Corridor

The Las Vegas to San Jose route is designed to capture the high-volume demand for travel between the "Entertainment Capital of the World" and the heart of Silicon Valley.

Route Details:

• Departure: Harry Reid International Airport (LAS)
• Destination: San Jose Mineta International Airport (SJC)
• Frequency: Multiple daily departures to cater to both business commuters and weekend leisure travelers.
• Aircraft: Boeing 737-800 and 737 MAX 8.
