When to go and what to expect
Chicago
Late spring through early fall is the most pleasant stretch. Winter brings snow and cold that can cause delays.
Las Vegas
Spring and fall are the most comfortable. Summer highs regularly pass 100°F, and winter evenings can be cool. Prices rise around major conventions, big sporting events and holiday weekends.
Getting between the airport and town
Chicago: CTA trains run from both airports to the city center, which is usually the most predictable option at busy times.
Las Vegas: Taxis, ride-hail and shuttles run constantly between the airport and the Strip.

Good to know
- Winter weather is the main source of disruption. Build in extra buffer for connections between November and March.
- Weekend flights are often busier, so a midweek departure can change the price picture. Ask about event dates before you lock in travel.
- Compare the total with bags included, not just the base fare. See baggage fees and taxes and fees.
