May is a popular shoulder season for travel from Baltimore/Washington International Thurgood Marshall Airport (BWI) to Harry Reid International Airport (LAS). Early May typically offers moderate fares and pleasant pre-summer weather in Las Vegas, while Memorial Day weekend near the end of the month often brings higher demand and premium pricing. Use flexible-date searches to find the cheapest May flights and opt for mid-week departures to cut costs.
Arriving at Harry Reid International Airport (LAS) in May is ideal for travelers seeking warm weather and early pool season events, but expect higher volume around Memorial Day and major festivals. Plan transfers in advance, especially if you’re heading to the Las Vegas Strip or a convention center. Booking ground transport and checking hotel check-in policies ahead of time avoids common arrival delays.
