✈️ Flight Guide: Spokane (GEG) → Las Vegas (LAS)

December brings high-profile events that can affect flights and fares on the Spokane International Airport (GEG) to Harry Reid International Airport (LAS) route. Las Vegas hosts holiday shows, New Year’s Eve festivities on the Strip, and various conventions that spike demand, especially during the last two weeks of December. Spokane’s winter holiday markets and nearby ski resort openings also influence departure patterns early in the month. Travelers should book flights and ground transport early, and anticipate higher airport volumes during event weekends.

The best time to fly from Spokane International Airport (GEG) to Harry Reid International Airport (LAS) in December is early in the month or mid-week (Tuesday–Thursday), when demand and fares are typically lower. Avoid the week between December 24–31 if possible due to peak holiday pricing and heavier airport traffic. Late evening red-eye and early-morning departures often have lower fares and fewer crowds. Book as soon as your dates are firm to lock in better rates and seat availability.

Tips

• Fly early December or mid-week for best value.
• Avoid peak holiday dates (Christmas Eve to New Year’s Day) for lower fares.
• Use flexible date searches to compare savings across a week.

Use mobile boarding passes, check flight status frequently, and consider travel protection for holiday travel disruptions.
