I was actually able to put my arms inside the armrests (middle seat) without crossing my arms in front of me. And I am not skinny. What a pleasant change!

This was my first trip on Alaska, and I was very pleased. The seats were wonderful...they felt ergonomic rather than too big (I'm small) or too cramped (even though I'm small, I hate when the seat in front of me goes back and I feel crushed). Good, friendly service. Informative messages from pilot. Easy check-in, Flight was slightly delayed and we were kept abreast of developments and told how we could cooperate to make boarding faster. Downside: no blankets and pillows for a redeye. If you don't want to provide them to keep costs down, let passengers know, so we don't keep blanket substitutes unaccessible in our carry-ons!

Flight was delayed but JetBlue was very accommodating and staff was helpful!

It was okay, bit squished but I wasn’t expecting anything else from the basic class

Jul 6, 2019

My kids want to have some games on the flight. ( I don’t really care)

Jul 5, 2019

Very smooth flight experience! Loved the free popcorn chips.

I really enjoy what JetBlue does with passengers being able to get their own snacks and drinks. A simple gesture like that creates trust and is really customer service friendly in this day and age of flying with the airlines. And I've never seen anybody abuse the privilege. It makes flying with JetBlue so nice along with the free movies. This airline is beginning to be my favorite among domestic airlines.

Jun 16, 2019

Nice to have meals on cross country flights!

You could make the seats more comfortable. I am 5'7" and thought u rarely an uncomfortable, this flight my tail bone was hurting me.

Flying from Seattle to Boston

Seattle Airport

While Seattle is home to several airports, the only one that handles commercial flights is the Seattle-Tacoma International Airport. Also known as Sea-Tac, this airport is responsible for all incoming flights, along with flights from Seattle. Alaska Airlines, Air Canada, Delta Air Lines, Southwest Airlines, and US Airways are a few airlines that operate out of this airport. Located in SeaTac, Washington, the airport sits along the intersection of three state routes: 99, 518, and 509. Though the airport has three terminals, only the Concourse Terminal and North Satellite Terminal handle domestic flights. The South Satellite Terminal specializes in international flights. It's just a short drive from the airport to downtown.


When you need to reach your hotel quickly, head for the public transportation system, which consists of Sound Transit and Metro Transit. The buses and light rails only cost a few dollars, and you can visit the sales counter at any station to purchase tickets for your trip. The light rail system drops passengers directly at some of the top hotels in the downtown area. Seattle uses a grid system for its roads, which makes finding your hotel easy if you drive. You can use the sign to look for rental cars from the airport.


If you visit during the spring, winter, or fall, you need a warm coat and an umbrella. Though the city does not get snow, it does get a high amount of rain during these seasons, and temperatures that can drop below 40 degrees Fahrenheit. The summer is much warmer, with temperatures in the high 70s and less rainfall.

Popular Attractions

Seattle is home to dozens of cultural activities and attractions, including the Seattle International Film Festival, the Henry Art Galley, the Woodland Park Zoo, and the Seattle Underground Tour, which takes you through older parts of the city.
