Flights from Massachusetts to Washington: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Massachusetts to Washington

Flying Alaska Airlines from Boston to Seattle was an example of getting exactly what you expect. A no-frills basic experience, but one where the important things were accomplished, timely departure, on-time arrival, no drama, no glitches, completely as anticipated. I paid a little extra for one offered perk (seat selection), and I'm glad I did because my early morning flight was full. Next time, I'll likely pre-order a snack, since they looked good, were served promptly, and are priced right.

It’s a good choice. Seattle airport is huge and confusing if you are changing planes. Have plenty of time to switch.

Flight was delayed 5 hours. Missed connecting flight. Very little apology or attempt to make anything better. Got a $150 credit for next flight. There won’t be another flight. First time on Alaska - last time. Keep your credit. Should have done something more

Flight was delayed 5 hours. Missed connecting flight. Very little apology or attempt to make anything better. Got a $150 credit for next flight. There won’t be another flight. First time on Alaska - last time. Keep your credit. Should have done something more

The crew the employees were friendly and excellent. There was a problem with the plane and they had workers there immediately working on it. They made sure the people that had immediate connects knew what gates they had to get to and had them leave the plane first. Very thoughtful.

We waited over an hour for our luggage to arrive at the carousel in Seattle.

Like the friendliness of the crew, each flight had a very very drunk person next to me and the last flight had a very obese man pushing me into the aisle while the crew kept ending up hitting me in the shoulder with the beverage carts.

Flight was about 30 minutes delayed. All staff were friendly and professional while keeping us updated.

My screen was hard to change channels….seemed it was worn out….i just gave up and read a book I brought

Booked a first class ticket from Anchorage to Seattle but was denied complimentary access to Alaska Lounge as our 1500 mile flight wasn’t long enough’

We were lucky to be seated in an upgraded row and received free drinks!!

Everyone was very helpful. My only critique was the very hard landing in Seattle. We felt the G force.

It was absolutely terrible due to the mother and her two children sitting across from us. The 2.5 year old jumped up and down on the tray table. Every time the kid screamed the mom would grab the kid and scream even louder into his face. Horrible flight. The mother stayed on her phone playing while the kids were so destructive to others hanging over seats, she never once tried to comfort or discipline them. She never once said you cannot jump on tray table. Definitely the worst flight ever. It was my first time with Alaska Airlines.

5 hours of delay that could've been much shorter if Delta had taken the 1 hour delay they imposed on the flight before boarding to run any of the plane checks required for flight to find the hydraulic issue that required nearly 3 hours to fix. $24 of meal credit buys a sandwich and a soft drink. Poor communication within the terminal about what gate we'd be re-boarding from and when we'd be re-boarding.

Food from the flight from Atlanta to Santiago was very poor..

The worst part was I was NOT allowed in the lounge even though I was holding a first class ticket and have a premium American Express card. I have flown Business or First Class with many airlines. Delta is the ONLY one who does not extend this courtesy to anyone except people who hold the very expensive American Express card. As a result, I won’t fly Delta if I have any other choice.

Thank you for not flipping the plane on the run way. You guys get a 5 star rating for the flight!!!

Seats are much much more comfortable than United, which is what I usually fly

Flight left early and arrived early. the whole trip was excellent.

Overall, it was okay. Seat was a little cramped. Would’ve liked more substantial snacks or opportunity to buy some.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

Delta was great the entertainment was outdated. Screen was very small and didn’t work.

The seats are uncomfortable, feels like a small seat pad on plywood.

Very nice experience. The boarding however seemed somewhat mixed up, and we were delayed taking off.

Flight was canceled with no voucher of any kind and next available flight was two days later.

Boarding was chaotic. Microphone not working properly and second agent was distracted from task with baggage and late arrivals.

I DID NOT GO TO HAWAII ON HAWAIIAN AIRLINES. YOU DID NOT INFORM ME THAT BY CHOOSING BASIC ECONOMY, I MIGHT BE REQUIRED TO FLY STANDBY. I AM ELDERLY AS WAS MY COMPANION WHO IS ALSO SEVERELY DISABLED AND THERE WOULD BE NO WAY WE COULD TRAVEL ON STANDBY. THEY TOLD ME THAT ALL OF THE BASIC ECONOMY SEATS HAD BEEN SELECTED BY OTHER PASSENGERS AND WE HAD TO PAY AN ADDITIONAL $942 TO GET A SECURED SEAT ON THE PLAN AND, IN SPITE OF THE ADDITIONAL COST, WE WERE NOT ALLOW US TO AMEND OUR TRAVEL PLANS TO EXTEND OUR VACATION. ULTIMATELY, THE FLIGHT WAS DELAYED. WE WERE OFFERED A REFUND IF WE CANCELED OUR TRIP ALTOGETHER WHICH WE DID. IT IS YOUR DUTY TO INFORM YOUR CUSTOMERS OF THE POTENTIAL PROBLEMS THEY MAY FACE, AND YOU DID NOT DO SO. I WILL NOT UTILIZE YOUR SERVICES EVER AGAIN.

It was very pleasant. The staff and crew are very polite.

On time. Alaska upgraded seat comfort with memory foam seat covers with head rests

the people at the counter, NEED TO BE MORE HELPFUL. we had three suitcases to check in and we were not trying to be an INCONVENIENCE TO YOUR clerks. but she was not helpful and made our trip back home memorable but not IN A GOOD WAY. Sadly to say, you guys need to teach to be and to go above and beyond to help THE CUSTOMER BY ANY MEANS POSSIBLE. they need to leave aside whatever they are going thru in their lives, THEIR WORK DEMANDS THAT OF THEM, IF NOT THEY ARE NOT IN THE JOB THEY SUPPOSED TO.

Because the airport is under construction and because Hawaiian air just changed terminals we missed boarding out flight by 5 minutes. That cost me a night in an airport hotel and several hours of rebooking to make it to my destination. Costumers need to know that airport construction is a problem and they need to add an hour to deal with the air train delays from Federal Circle.

Half of my family members didn’t make it because they involuntary bumped off . And their seats where given away

Hawaiian Airlines staff is always professional & quick & easy check in & boarding process

Communication since no reason or explanation was given for 3 hrs delay

Flight was delayed several 3 hours - no reason was given and no communication what so ever.

No overhead baggage room even though I was seated in row 2. Consequently had to check in my carry on bag. Baggage carousel was jammed. Took 45 min to get my bag.

Excellent from start to finish. All staff members were amazing!

Excellent. Although they used to greet me as a mosaic member and provide a free drink, early boarding helps me to keep coming back to JetBlue.

Cancelled flight with no specific instructions to get a boarding pass for another flight. The whole flight of people were in line for an hour because there was only 1 person to help at the desk. This was unusual for JetBlue.

It was too hot in the cabin. The AC did not help.

Except for the 28 minute delay leaving and the earlier reschedule to a later takeoff time the flight was good.

Loved the leg room and tvs screens on the seats and free WiFi. Wish the price was lower and could save by rebooking

It took 1-1/2 hours to get our luggage after we landed. That to me is unacceptable

5.5 hour delay with no explanation on why, along with no proactive effort to reaccomodate me.

It was one of my worst flight ever. First they were changing the gate for at least 4 times, changing from gate D7 to D12 to D44. Considering the size of the Miami Airport, we are talking about long distance and the train at the airport was not working. Then the flight was delayed around one hour. Then finally we boarded into the plane and when everybody was seated, there was an announcement that there is an issue with one of the tire of the plane, so we all had to get out of the plane with our belongings, to replace the tire. So we had around 2.5-hour delay

Most miserable flight ever. We waited almost 2 hours on the runway because the flight was oversold. American offered $1200 credit. Then there was some nonsense about weight distribution. Ridiculous. No food for 8 plus hours on the flight. I will be writing a letter.

Honestly, I haven’t flown American in years, probably due to the pandemic and my being unable to travel for certain periods in the last two years, but it was a good experience to dig out or obtain a new American Airlines account after many years of traveling for business with American in the past.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious.

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious. this return flight not as tasty, but filling.

The flight was 2 hour delayed, otherwise everything was excellent. The delay was due to the hourly limit requirement so given that as a reason, I'm happy with the flight!

Weather delay for 2.5 hours followed by half hour crew delay, did not have ginger ale, uncomfortable seats

So awful Unreliable Unfriendly Bad Mad Mean Smelly Hot Late Overbooked Understaffed Expensive Cramped Narcs If they were a fruit they’d be rotten durian
