Boise: May brings the start of the Boise Farmers Market, spring blooms at the Idaho Botanical Garden and Memorial Day weekend events that increase hotel and flight demand. San Jose and the Bay Area: May features Cinco de Mayo community events and a variety of cultural festivals, along with university commencements that can affect local car and flight demand.

Nonstop flights from San Jose (SJC) to Boise (BOI) save time (typically under 2 hours) and reduce the risk of missed connections, which is helpful during busy May travel periods. Connecting flights often cost less but add total travel time (3–6+ hours including layovers) and increase the chance of delays, especially through hubs like SEA, SFO, PHX or SLC. For short regional trips in May, prioritize nonstop service when convenience and time savings matter; choose connections only if the fare difference is significant. CTA: Compare nonstop and connecting options for your May dates to find the best balance of price and schedule.

Alaska Airlines: Often offers the most dependable nonstop schedules and a strong loyalty program; expect standard carry-on and checked bag fees for Basic fares. Southwest Airlines: Competitive pricing and two free checked bags on many fares, often the best option for families; check which Bay Area airport is used in SJCA searches. Delta/American: Typically route travelers via Seattle, SFO or Phoenix with regional partners — good for connecting itineraries and mileage credit but may have variable baggage policies. For May travel, review change and cancellation flexibility and consider the total trip cost (tickets + bags) when choosing a carrier. CTA: Compare total cost and schedules across these airlines before booking your May trip.
