FAQs - booking Puerto Rico flights

  • Are there any direct flights from Seattle to Puerto Rico?

    As it stands, there aren’t any airlines that are offering direct flights from Seattle to Puerto Rico. To get to Puerto Rico, you will have to deal with at least one layover during the journey. The airport in which you will have your layover depends on the airline you’re traveling with since each airline has its preferred destination. For example, when flying with JetBlue, there’s a high chance your layover will be at Boston or JFK, while all flights by United Airlines have their layover scheduled for Newark Liberty.

  • Does SEA have any airline lounges?

    Alaska, Delta, and United Airlines all have a lounge at SEA Airport. Alaska has three lounges in Concourse C, Concourse D, and the North Satellite, respectively. Concourse A hosts the Delta Sky Club and United Club, which can be found near Gate 1 and across from Gate A10, respectively. There is also a Centurion Lounge, USO Lounge, and The Club at SEA in the central terminal and south satellite.

  • Does SEA Airport have any onsite hotels?

    If you have an early flight from SEA, the best place to spend your night would be at Coast Gateway Hotel. This is the closest hotel to the airport, putting you less than five minutes from the main terminal. By staying here, you’ll be cutting down your commute, thus reducing any chances of missing your flight.

  • How do I get wheelchair services at SJU Airport?

    SJU Airport provides free wheelchair services to all passengers with limited mobility to help them get around the airport with ease. You can request a wheelchair at the airport information desk which is in Terminal B near the ticket desks. You can also reserve one through your airline so that it can be ready for you as soon as the plane lands. This, however, should be done at least 48hours before the scheduled departure time.

    KAYAK is a travel search engine. That means we look across the web to find the best prices we can find for our users. With over 2 billion flight queries processed yearly, we are able to display a variety of prices and options on flights from Seattle to Puerto Rico.

  • What is KAYAK's "flexible dates" feature and why should I care when looking for a flight from Seattle to Puerto Rico?

    Sometimes travel dates aren't set in stone. If your preferred travel dates have some wiggle room, flexible dates will show you all the options when flying from Seattle to Puerto Rico up to 3 days before/after your preferred dates. You can then pick the flights that suit you best.

Top tips for finding cheap flights to Puerto Rico

  • When flying from Seattle, you will most likely depart from Seattle-Tacoma International Airport (SEA). This airport facilitates most domestic and international flights from Seattle, so you should ensure that you arrive at least two hours in advance so that you can have enough time to go through security.
  • When booking connecting flights, avoid those with a self-transfer option. These flights require you to check yourself and your bags into every individual flight, and that can be quite stressful and inconvenient.
  • Book a flight that lands in Aeropuerto Luis Muñoz Marín (SJU) as that is the main airport in the country. From here, you can get connections to virtually any region of Puerto Rico, either by air or by road.
  • While public transport is available from SJU Airport to the city center, you can’t use the bus if you have more than one piece of luggage. The best alternative, in this case, would be taking a taxi or hiring a rental car from one of the airport car rentals.
  • SEA Airport has a range of long-term parking options for anyone who wants to leave their car at the airport. However, you are advised to reserve your spot in advance so that you can have an easier time once you arrive at the airport.
