The airport lies about 10 km southeast of central Riga; travel to the city center usually takes 15–25 minutes by taxi or 20–30 minutes by public bus and shuttle. City buses and minibuses are the most budget-friendly option (fares are typically modest), while taxis and ride-hailing can be quicker but pricier. Strengths include compact terminals, straightforward transfers and regular international connections; downsides can be limited late-night services and occasional crowds during peak summer months.

The airport generally balances convenience and capacity — arrivals and transfers are usually straightforward, though peak periods can feel busy; budget travelers may find good low-cost options while those seeking more premium services can use full-service lounges and frequent-carrier routes.
