Airport Information
Miami (MIA)
Miami International Airport (MIA) serves as the primary gateway to Latin America and the Caribbean, but it is also a massive hub for domestic travel, particularly for American Airlines. Located just eight miles northwest of Downtown Miami, the airport features a wide array of high-end shopping, diverse culinary options reflecting the city's Cuban heritage, and multiple luxury lounges. Travelers should arrive at least two hours early due to the large volume of international connecting passengers that can impact security wait times.
Seattle (SEA)
Seattle-Tacoma International Airport (SEA), commonly referred to as Sea-Tac, is the largest airport in the Pacific Northwest and serves as a primary hub for Alaska Airlines and Delta Air Lines. The facility is renowned for its impressive art installations and the Central Terminal's massive glass wall providing views of the airfield. Visitors can easily reach downtown Seattle using the Link Light Rail, which offers an affordable and scenic 40-minute ride from the airport station to the city's heart.
