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

Insights shared by verified travelers who flew the route from Boston to Washington 
Verified travelerFlew with Alaska AirlinesBOS-SEAOct 2024
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.

My flight was delayed 2 hours which led me to lose my connection. As a consequence, I had to spend hours changing flights and hotel reservations to arrange my arrival to Vancouver.

My flight was delayed 2 hours which led me to lose my connection. As a consequence, I had to spend hours changing flights and hotel reservations to arrange my arrival to Vancouver.

No Free Wifi and the flight was a tad late.

The plane was clean. They got us to the destination. It was very difficult to hear the announcements at the gate. The person was speaking way too quickly, and the sound system did not carry to all parts of the seating area at the gate. The flight left more than an hour late, which left many of the passengers missing connections.

The flights left both airports on schedule. The flight from Idaho Falls to Seattle was a typical commuter trip. The flight from Seattle to Maui was not good: It was too long for a flight in a single-aisle plane and too cramped. I kept asking myself if I would ever visit Maui again if airlines continue to run this long flight like a typical short commuter flight. I am not looking forward to the trip home.

The chicken salad was very small, the lettuce was wilted and there was no flavor. The hamburger was excellent.

Flight attendant was awful, I felt second hand embarrassment with every one of her interactions with people onboard. She was so incredibly rude every chance she got

It was a good experience! Thank you:) No sparkling mineral water… 🥲

Mid flight we were bothered by a bee. Kind of odd, but a bee allergy made it a bit stressful. Attendants passed by our aisle during service multiple times. Otherwise, it was fine.

5 1/2 hour flight with no food service or options is inexcusable.

Great flight - efficient and cheerful team on board, at SFO gate. Also, PAE (Paine Field, Everett, WA) is a great little airport to fly out or in to!

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Delayed and took off even later than the scheduled delay time

Only issue was with seating. The economy fare we purchased did say there was no guarantee the three people in our party would be seated together, and we were not. At the gate, the agent told us more specifically, the fare we purchased meant we would be seated in middle seats only. This should just be made more obvious.

this crew didn't care much. bumping carts into seats more times than i care to remember

Everything was fine except the entertainment was not working for half of the flight.

There was a security issue at the airport and we were unable to land. We circled endlessly and then landed at another airfield for fuel. We then circled the airport again, almost landed but didn’t fully touch down before circling again. I am thankful to the crew for keeping us safe- the issue was the airline and staff at the airport getting us seats on our connecting flights. That part was hours of searching for someone and getting in double my steps.

Boarding was organised and relaxed. Crew were fantastic! Seats were lacking padding causing butt pain and stiffness.

I want to single out flight attendant Mitch who was in the Premium Economy section. When my wife’s hearing aide dropped through the cushion under the seat he was able to locate it and return it to her. Food was a different matter. Dinner was fine. Breakfast was another matter. They had a yogurt dish that the ran out of and the alternative was not very good according to those we talked to.

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.

Great flight! Only complaint I had was that I didn’t get breakfast that morning because I don’t eat eggs for breakfast.. I ate an energy bar I bought in the airport which I had never done before. Otherwise, another great Delta flight!

First class ticket. They ran out of food and I sat hungry watching the others eat

They we able to seat my companion and I next to each other. Plane’s temperature was very cool. Willl be more prepared on return trip.

All was good and they were able to seat my travel companion next to me. Thank you.

Like the ample leg room. May as well not bother with snacks if it's only a two ounce bag of pretzels. Didn't use the entertainment option. Was there one?

What an amazing flight. I haven’t experienced this level of service in a flight in years. This will be the only way to fly to Hawaii for me in the future.

Kayak sold me a ticket after check in time. Could not check in. Could not get on flight.

Love you guys are so friendly and kind and wonderful

Agents talk too fast over intercom. I know it’s memorized and we’ve all heard it before. Just slow down a little. Stop charging for checked bags. I was pleased to get my bags promptly at each end of my flight.

Everything was great except having to check in at Alaska. That was a surprise and took extra time and effort. Should have been explained somewhere maybe on the HA electronic ticket.

It was clean and the crew was great. I wish the chairs could recline just a little more and you would provide small pillows for people with bad backs. My back is fused and a little support would be great.

Given it’s a red-eye into Charolotte, we didn’t get any food. The survey does not include “N/A” so the rating will be skewed.

Great. Quick and quiet and east. The breakfast choices were a welcome surprise!

American airlines suck they delay the flights all the time made me sleep in an airport because my flight was delayed and I miss my connecting flight

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

The stewardess hit me with the food kart twice on the head and didn't say I'm sorry once. The same stewardess gave me a warm Apple Juice with No ice. The Flight was delayed for Departure 6 times, starting from 2:36pm, finally taking off 7:50pm. I was late picking up my child from the sitter by 3 hours.

Having to reschedule flights a day later, they loaded by luggage on the wrong plane from Little rock now I have to HOPE they deliver it to where im staying like they said would. International flight crew was very disgruntled and not very friendly.

We will be writing a long, detailed letter to corporate about our awful experience with American airlines.

It took way too long to diagnose and solve the problem of a broken crew member cabin seat. Though compensation for the volunteer who left the flight was very kind.

The entertainment package was vast and the selections were very current. Keep updating it was great.

The seat was so hard my tailbone was aching The crew was kind of a b**** because I made a joke that I didn't care if they close the door I total c*** when she was trying to f****** act like she was mad at me because I said that The flight was bumpy. Sure you didnt have control over that.

They have the most inexperienced / rude flight staff I’ve encountered

very difficult boarding process - aggressive passengers not the friendliest crew

WiFi was not eorkig (again) And the plane was from 1990 with the screens which were.not touch and most didn’t even work and if lucky could tune in tv

I paid extra for a seat closer to the front. The TV didn’t work at all for the entire flight. Would have been nice to know before I purchased an “upgraded “ seat

It was great. I had never flown on JetBlue before, but would be very happy to fly with them in the future.

Worst flight experience ever flights canceled. JetBlue told us just did not even bother standing in line to come back in one and a half hours then without any information we had to go pick up all of our luggage and spend over $2000 in accommodation just to get home. JetBlue said that the next flight available for us to get home would be three days later. Absolutely absurd hasn’t offered to give us any compensation do not fly JetBlue horrible company. They said it was based on the weather and the weather is great in all locations that we would’ve been flying to total hoax. I think it’s a conspiracy theory.

The captain gave good announcements and the flight attendants were friendly. The WiFi was pretty good. The plane itself looked very old inside and the seats were very uncomfortable. The screens in the seat backs were the smallest I’ve ever seen. There were so many loud and obnoxious kids on this flight and the parents didn’t do much to try to quiet them down. Some had videos and games on tablets with higher than necessary volume going the whole time.

Too many long delays with JetBlue. Worst major airline that serves JFK but unfortunately I keep going back because of the prices.

My JetBlue experience was nice. The flights ran on time, the aircraft was clean and comfortable, and the flight attendants were attentive. My only issue, which is isolated to the low-cost (budget) option at JetBlue, is that the check in process makes the user feel that they have to buy their seats. The seats offered for purchase are upgrades from the budget seats you get (which are essentially the last seats remaining). The interface should not make it feel like you must purchase a seat.

The plane was late to leave.. Internet was lousy. TV was not working. when we arrived, We stayed on the plane for a long time before we got to the gate. It took us a long time to retrieve our luggage because they didn’t know what carousel to send them to. It was a bad experience.
