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.

The flight was canceled at the last minute and we got very upset as we had plans in which our schedule that affects a family reunion was in jeopardy.

The flight was canceled at the last minute and we got very upset as we had plans in which our schedule that affects a family reunion was in jeopardy.

Paying for first class and then they want $8:00 for wifi.

10 hour delay. Fuel spill. Crew had to drive to Indianapolis to a get a plane. The longest day of travel ever. Poor service.Little to no communication.

I'm so glad that Alaska still keeps this little "puddle-jumper" route going between SEA>ALW; my daughter lives on Walla Walla, and it's so much quicker to be able to fly right in to Walla Walla than to have to fly into Tri-Cities and then make her drive 40 minutes each way. This flight is usually only 50%-75% full when I fly it, but that's because it doesn't get in to ALW until MIDNIGHT! But thanks for continuing to service the Walla Walla area, Alaska!

Easy flight, crew was polite & observant of all passenger needs as well as safety.

fine. only problem,,,, for some,,,,was that many people started trying to exit from the back of the plane,, . lots of irate people. there should be a flight attendant mid plane..to be sure that doesn't happen. The crew up front had no idea what was happening. One big guy started it..then a bunch of others followed his lead. could have gotten ugly... One man stepped in and questioned those rule breakers.. nothing bad happened,,,but......

We were delayed. We spent more time waiting on the plane than actually flying (it’s only a 37 minute flight). Other than that, it was fine.

Only offered water, no snacks provided, and it was cold on the plane, everyone was wearing sweatshirt or jacket in June. I asked for blanket, but crew said they didnt have anything and would turn the heat up, that didn't happen, so for 6 hours I remained cold.

Flight from New Orleans to Seattle to Anchorage was delayed for 3 hours My flight from Seattle to Anchorage was not rescheduled. I had to call the airlines to tell them to get a flight from Seattle to Anchorage they finally got me a flight If I hadn’t been aware of this problem I don’t know how long I would of waited in Seattle to get a flight to Anchorage!!!!!! Return trip from Anchorage to New Orleans in Seattle to New Orleans I was at the right gate when I realized something was wrong they had changed the gate without notifying the change l finally made it on time with minutes to spare & exhausted

I was at risk of not getting on the flight, as when I presented my boarding pass at the gate, it showed me as not having checked in. I was sent to the desk as the last of the other passengers boarded. The agent there said he could see that I had done all of my part and allowed times recommended, but it showed me as not checked in and he couldn't figure out how to correct it. He actually asked them to hold the flight as he struggled with it. He called for support, someone corrected it, and he printed boarding passes for both flights to reduce further issues. I did get on, and needed to ask someone to exit my seat.

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.

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.

I was put in seat 6B with no warning. Had no seat in front of me just sticks out in the aisle so I had to hold what I could and put the rest in a bin way further down.

I was traveling with my two young children and brooked this flight as it was the best option. There were no screens for movies etc. which normally would be fine, however, when you list free in flight entertainment that should be mentioned. We don't rely on them but count on it as a worst case scenario backup for the kids to keep the peace if needed. The main issue though was the food selection. I have dietary restrictions so I was excited to preorder meals. Nothing that was offered on board or for preorder was ok for me to eat, not even the snack boxes. It was very frustrating for a 5+ hour flight. Otherwise the flight was good and went smoothly.

Usually we have a pleasant trip on HA. Not this time! All stewards were unpleasant, rude, rushed, condescending. First step onto the plane, WE greeted the crew with an “Hello!”. They greeted us with a terse smile then ignored us. Not a good start. Even over the PA announcements, they were rushed and unpleasant. One Stewart even berated a passenger in front of us when all they asked is if the purchase cart had vodka to purchase. The steward said “LIKE WE SAID OVER THE PA, THIS ONLY HAS FOOD OR BEVERAGE!” Vodka is a beverage! It was a legitimate question. Not sure why she treated the passenger this way. Taking trash was even unpleasant, No “Thank you” or at least a smile. I work in CS. I know good CS can make or break your trip. There was absolutely no “aloha” on this trip. All clearly did not want to be on this plane and felt strongly that they did not want to provide a premium service to their clients. This might be our last HA and cancellation of my HA-MC if we are treated the same way going home. We are typically treated with kindness and warmth in the past with HA. This trip was unacceptable.

Plenty of overhead compartment room. The seat choice option is horrendous as best.

Really disappointed with in flight entertainment, 6 hr flight with no built in screens

I was put in a middle seat with the people on either side of me kept passing their grandchild over me and talking back and forth while I was trying to rest or watch a movie. So inconsiderate and totally disturbing. I asked if they would sit next to each other to alleviate the constant impeding my comfort but they refused.

The flight crew were great. Very helpful and friendly. Seats comfy. Thanks

Overall it was a good flight, but the food should be looked at. No options. The seat was also uncomfortable and very tight.

Late boarding, full flight. Absolutely no food and barely a bag of pretzels. No video screens and slim pickings of movies. No live tv and poor selection of shows.

It’s great, I’ve always fly & ride with Hawaiian Airlines going Inter island or to the mainland.

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.

I especially liked the lead crew officer. His boarding and safety announcements were made with a bit of novelty and humor. The flight also left the gate 10 minutes early and we landed about 20 minutes early… It was a delightful flight…

There were mutliple delays. There was inconsistent, delayed, and poor communication regarding the delays.

Spend hours delayed with no food, water anything sitting on the aieplane with no ability to eat or use the restroom. My entire experience was the absolute worst. I will never fly jet Blue again.

It would have been nice if they had offered more than one set of snacks

Seats were not too comfortable; it was impossible to locate the underseat power outlet.

You get what you pay for with JetBlue. Every little thing costs more, you are nickel and dimed until the end. Entertainment doesn’t function. Flight attendants do the bare minimum.

The check in and boarding process was a bit of a cluster. Two people at the counter to check in, three random lines that nobody knew which was for what, and people kept getting shuffled from one line to another for no apparent reason because then they’d get shuffled back and end up getting out further back in the line than they were originally. I only had to hand my already checked bag over and it took 45 minutes. I was never assigned a seat so when I tried to board I was pulled out of line again while someone had to try to manually assign me a seat. During the flight I got up to go to the bathroom, and there was an attendant in the aisle offering pillows etc and it was a 30 min wait unbuckled standing by the bathrooms because she said I couldn’t go past her. First and last time flying jet blue to be honest.

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.

Overall fine, but the delay was annoying and the reasons for the delay were not communicated. The crew on board were phenomenal!

Flight delays numerous times. Everytime we would get close to boarding it would be delayed again. Strung along the entire time.

After a two hour delay, my flight was CANCELLED! No pilot available. Such BS.

Overall very good, only complaint I have is the crew from CLT to SAT could have collected trash sooner.

The AA app really sucks ... Every flight & connecting flights were delayed over 30 mins. One connecting flight on American Eagle said it was delayed in its arrival ... when it was actually parked across from the gate for over 1 hr before they pulled it to the gate. Seats in the economy/ main cabin are packed together like sardines ... no leg room.

Initial flight was cancelled at the time of arrival to the airport, flight alternative requires switching from direct to flight with a layover, and the plane felt like it would split apart, it was so rattle-y.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

AA re-routed flight from HNL to LAX due to delay. My group of 3 with reserved seats in row 9 was broken up, with one assigned to a middle seat, another in the last row of the plane. Not happy. No explanation to the delay. No apologies. No compensation. Would have been nice to be offered an Admiral Club admission or a voucher for the extra 3 hours of layover in LAX. Could not hear the boarding gate announcements in LAX. Adjacent gate was boarding at the same time. Loud speakers were competing against each other. Barely made my boarding group.

Boarding gate in Honolulu was staffed with a great clerk with a soothing voice despite the flight delay of over an hour. Flight attendants in the plane were all grumpy, not pleasant looking bunch. Their sour attitude showed throughout the flight. Inly able to get a select few movies started. Most of the movie links in the “free entertainment” did not work.

Above and beyond effort from this crew in a tough situation. So helpful and understanding. Thank you!
